By Karen Rought (@Karen_Rought) at 10:45 am, October 8, 2013 | Reviewed by Brandi Delhagen

With the release of House of Hades comes the title of the fifth and final book in the Heroes of Olympus series by Rick Riordan.

The title of the final book will be The Blood of Olympus. It will release in the fall of 2014 and conclude the Heroes of Olympus series.

Having not yet read House of Hades, and obviously knowing nothing about The Blood of Olympus, our guesses as to what the title could mean are pretty basic. On the one hand, it sounds ominous. Could Gaea and her minions be attempting to slaughter the gods on Olympus, spilling their immortal blood and taking over?

On the other hand, perhaps it’s more metaphorical. Maybe the demigods are the “blood” of Olympus — that thing that keeps the whole network going, the heart and soul of the contemporary Greek mythological world.

Unfortunately, it looks like we’ll have to wait a whole year to find out. But never fear! In the meantime, get your hands on House of Hades, which releases today. We’ll have a spoiler-free review up as soon as possible.

If you’re fuzzy on the details from Mark of Athena, the third book in the Heroes of Olympus series, be sure to check out our guide, which will tell you exactly what you need to know in preparation for House of Hades.

If you’re like so many others and can’t get a copy of House of Hades just yet, you can bide your time by staring at the beautiful character portraits of Eros/Cupid and Nyx, both of whom will show up in the fourth installment.

However, be wary of the comments section on any of our posts, as people may be posting spoilers for House of Hades. Peruse at your own risk!

What do you think of the title for book 5 in the Heroes of Olympus series?

  • http://ravenclaw1991.tumblr.com/ ravenclaw1991

    Well, that’s terrifying and heartbreaking already, isn’t it?

  • Gavin Walsh

    Sounds gut renching indeed

  • ZofTheTwiHard

    The Blood of Olympus… well, Gaea planned to spill some blood up there. Someone’s gonna die, I think. But I have no idea – I literally just got the book…

    • WisdomWarrior

      OMG!! I can’t believe I finally have the HOH. I can’t wait for the B.O.H. I think someone will die like maybe Hazel or Annabeth or ???? But I think that maybe Rick will make a villain but honestly I’m not telling the whole truth the book is on good reads going to read it gtg

      • Jordan

        He would never kill Annabeth! Are you insane?

    • awsomeness

      you got the book where I NEED to read IT!!!!!!!!!!

      • nicolover 23

        I NEED the Blood of olympus can u tell me where u got it

        • nicolover 23

          for an oath to keep with a final breath I think Jason because in the lost hero remember he promised piper a new snowboarding jacket

          • Jack

            Seriously???? How can you honestly think that? It’s the most insignificant oath. What about percys to Annabeth that they’ll never get seperated or Leo’s to Calypso?

          • Pedro

            How about Percy swore on his life that the Argo II landing on Camp Jupiter was not a deception. Hazel said Romans take an oath seriously. I don’t think Octavian is cutting him some slack.

    • Sanath Pise

      The bood of olympus is out?

  • Emma

    I just finished reading HoH a few hours ago–don’t worry, no spoilers, but I will say it was REALLY good.

    • D


    • Johanna

      It was so good!!!!!!!! My heart broke about twelve times, but I loved this book! Oh, Nico!

      • Emma

        I’ve been freaking out about Nico ever since I read that part!!

        • Bella

          Same here! I think I’m going to die waiting this new book to come out…… I mean seriously rick, what’s up with all these cliff hangers! I really want to read the 5th book….. I’m going to die waiting.

          • Emma

            At least there wasn’t, you know, a literal cliffhanger like in MoA.

          • dani

            i mean seriously MoA was the must mean clifhanger ever!!

          • SamTheDude

            I KNOW the first seres was all battel done battel done this one is batt-done batt-done AND I CANT WAIT FOR THE NEXT BOOK

        • Anthony

          that was supposed to reply to you sorry

        • HOHlover

          who hasn’t been freaking out!?

          • Emma

            It’s been three weeks and I’m still freaking out!

          • Allison

            I think I’m Gonna go insane waiting for the book

      • Anthony

        same with me Emma i had to stop reading for a while just to process it!

        • Emma

          I seriously need to reread all the books now and analyze everything with this new information

      • Alicia

        Oh my flipping gods nico!!! I really want a chapter from HIS perspective. Especially with everything going on…. Ugh I can’t stand thissss

        • PERCYLOVER#1

          I know right why does he have to be so freaking mysterious?! I wish they did one chapter on his perspective, I mean honestly, don’t leave us in the dark Rick!!!!!!!!!!!!!!!!!!!!

          • wisegrl/percyfan

            SAME HERE.

          • Daniel Bucher

            I completely agree with everyone!!! Waiting for fall of 2014 is going to be TERRIBLEEEEEE!!!! I’m TOTALLY freaking out about the nico part too!!! I’ve always been a Nico fan, but this twist has made things more interesting to say the least!!!

          • Mica

            What if the Blood of Olympus is about Nico’s POV?

          • Sanath Pise


          • Jojo

            No offense, but i personally don’t mind Nico being gay.
            You’re just being sexist.

          • Ted

            I know I thhought Nico was cool before the Gay incident. He should date leo since leo s the only single

        • NICO <3

          yeah totaly like cum on rick v need to kno what HE THINKS!!!!

      • PERCYLOVER#1

        It took a lot not to cry during this book, I bet the Blood of Olympus will be worse.

        • HoO <3

          DONT SAY THAT

    • Jay Yun

      Yeah, I agree it’s amazing



    • Johanna

      there’s actually no cliffhanger at the end of this book, literal or metaphorical. which is a relief. but don’t worry, it’s still gut-wrenching.

      • PERCYLOVER#1

        If it’s not a cliff hanger then what happens with Gaea?

  • Sadie

    The Blood of Olympus….I can’t wait!!!

  • Pipwig

    We are going to die from waiting for this aren’t we?

    • Teva Woolf

      Yes , I think that will be the case

      • PERCYLOVER#1

        I think I’m already dead.

        • YoloGen

          the how did you type

          • PERCYLOVER#1


          • ido erez

            he proably found annabeth’s laptop in tartarus

    • Jojo


  • Kiki

    It means the two demigods’ blood needed for Gaea to rise. It was explained in House of Hades. So you should of read it.

  • hello

    Bob says hi to the stars

    • Juliet

      Bob… :’(

      • Jojo

        Hopefully Bob and Damasen get out of Tartarus in Hypable.

    • Legendary#1

      Bob says hello to the sun

  • hello

    the cliffhanger is: “the argo II sailed on”

  • Lovepercabeth

    Awesome book!!! I feel bad for nico a little though :( but me and my friend couldn’t stop cracking up we had another theory that book had a lot of twists and turns can’t wait for the 5th book!!! Im gonna die waiting

  • Anthony


  • casama3120

    the blood of olympus is in reference to the two demigods (1 male and 1 female) that have to be killed and bleed onto gaia in order to fully wake her, this is mentioned briefly in MoA when gaia decides she wants percy and annabeth, but it emphasises it a bit more in HoH and is brought up several times, of course evreyone can only speculate as to which two it will eventally be (unless Rick suddenly changes personality and decides he’ll be lienient and so wont give us heartbreaking death scenes in BoO – what are the chances?)

    • xyz

      Maybe the two demigods are nico & reyna.Well,there is a possibility of everything!

      • PERCYLOVER#1

        I know right!!!!!!!!!!!!!!!!!!!!!!!! It might even be Thalia honestly, I think she’ll make an appearance in BoO.

  • fongamanda

    I chewed through HoH in 4 days…. now I have to wait a YEAR for BoO?????? Omg, too long!!!

  • mmudry

    I just read the book. i setsyour heart beating. it is awsome!!!
    Personally I think Hazel is the true hero in this book

    • Daniel Bucher

      I agree mmudry!!! Hazel learns to manipulate the mist (something she has never been able to do) in less than a month and defeats a powerful immortal sorceress. I love this girl, not to mention she is the only one who really stands by Nico that doesn’t know his secret. I know they’re siblings, but still, its’ admirable.

  • mmudry

    I can’t wait for a year for the next book! I will DIE!!!

    • #1fanofpercy&annabeth

      SAME HERE.

  • percabeth01960

    “back from tartarus!”leo whooped.”thats my peeps
    Lol leo

  • Al Verhey

    I was so disappointed when it said Nico was gay.


      Same here, I thought it would be great if Reyna and him started dating, they have so much in common.

      • team Leo

        err.. don’t think so.. Reyna and Nico together? creepy..

        • PERCYLOVER#1

          Come on I think it would be a great idea. Think about it. They’re both alone. Reyna left shouldering a job for two people and Nico because no one will except him. And honestly I think that Rick put them together transporting the statue. But if you think that’s such a bad idea what’s your solution?

          • Daniel Bucher

            I actually agree with you PercyLover#1, about when you said, that Nico should have been with Reyna…however, I wasn’t disappointed when I found out Nico like Percy. Percy IS a totally awesome and powerful demigod, so its not that odd in my opinion that he would develop feelings for him. I still want Nico to have a happy ending though.

          • PERCYLOVER#1

            Um I agree with you that you agree with me, and if Nico were like a GIRL it would be fine liking Percy , but he isn’t so it’s not. I don’t even see why Rick made Nico gay, it’s a little unsettling. (BTW 290 days till BoO)


    I can’t believe all the cliffhangers in this series, in the Percy Jackson and the Olympians series there was barely any except for the ongoing Luke problem. WHY???????????????????????????????!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  • wisegrrlfan

    I CAN’T WAIT TILL THE BOOK COMES OUT!!!!!!!!!!!!!!!( Blood of olympus i mean. I already read house of hades.)
    I am the hugest fan of rick riordan.
    ALL HIS BOOKS ARE SO SO SO SO SO GOOD!!!!!!!!!!!!!!!!!!!!!!
    Though i didnt like the kane chronicles very much.

  • percyfan#1

    greatest. fantasy. book. that. will. be. in….


    I fucckin cant wait for THE BLOOD OF OLYMPOS…


      With the cussing removed HECK YEAH!!!!!!!!!!!!!!!!!!!!!!!!

  • HOHlover!

    asdfghjkl what Nico says about Percy!!! Why Rick, WHy?!? he just loves to torture us!

  • only one use

    Why me?! Why Nico?! Why another year?! Why rick?! Why now?! Why man?! Just why?


      Well said.


    I know it’s a little early but does anyone know the actual release date yet? I’ve been looking everywhere for it so I can start counting down the days.


      Actually I think I found it Oct. 7 2014. Correct me if I’m wrong.

    • teamLeo

      yup.. it is 7th Oct 2014.. start counting guys…

      • PERCYLOVER#1

        331 days O my gods!!!!!!! I will post here every time I can kick my siblings off and update you guys on the days. I can’t stand this!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

        • PERCYLOVER#1

          P.S. GO TEAM LEO!!!!!!!!!!!!!!!!!!!! Love that guy.

          • KING K

            I think that when reyna brings the athena parthenos back to camp hb. The gods will be healed of their split personality thing and help the demigods fight their banes in Greece


    I just finished reading the book (HoH that is) for the eight time and I still can’t process it. I can’t wait one more day much less a year for BoO.

  • Tyler

    Why does the book have to take sooooooooo long.


      How is it long? I read that book in one day. SO AWESOME!!!!!!!!!!!!!

  • iluvbooks


  • FDIC

    Nicos gay


      Way to state the obvious.

  • Muahahah

      How do you know or are you just guessing?

      • TEAM LEO !!!!!!!!!!!!!!!!!!!!!

        yea how do you know

    • Nico is gay wtf i just died

      No dude, even if he’s dead, he’s still the son of hades. He can go to the mortal world again through shadow traveling.

  • BooksLover

    What are you’re guys’ ideas about Nico. He can’t disappear, that’s for sure. And he can’t have Percy. Personally I think he and Reyna should start dating but team Leo doesn’t think so. What are your opinions?

    • fas sihah

      i think, nico will fall in love with someone.. it will be most likely reyna.. personally, i don’t think nico is gay but he just admire percy as a hero.. u know?

      I wish but I doubt it. Fighting Tartarus. Bob was my favorite character I cried when I read about him dying. SO SAD!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  • Daniel

    Who do you guys think “keep an oath with a final breath will be?” HoH reveals so many more possibilities. All these promises being made…… WHO will it be? o: I think it’ll be Percy,


      I think it’ll be the promise of Jason to Piper or the promise of Leo to Calypso. But who knows?!

      • TEAM LEO!!!!!!!!!!!!!!!!!!!!!!

        i think it could be coach hedges promise to his girlfriend the wind spirit. cuase ricks been abit mysterious about that

        • TEAM LEO!!!!!!!!!!!!!!!!!!!!!!

          someone reply to this please?!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  • HeroesOfOlympus 13

    brillent for anyone who hasn’t read it yet. So for all the Hollywood Producers, finish Percy Jackson & the Olympians and get onto the Heroes of Olympus series.


      They really need to hurry with the Titan’s Curse and do The Battle of the Labyrinth and The Last Olympian before Percy, Annabeth, and Grover start looking their age (21,27,29) so they can still do the Heroes of Olympus or they need new actors even if that does totally botch it up (I mean even more so.) But I agree the Heroes of Olympus books will be AWESOME as movies.

  • Nicorocks

    Wow that book was good I can’t stop thinking about what happened with nico that was a total shock to me and can’t wait for the next book

  • Nyx

    What happened with nico was a total shock to me I an going to die waiting for the fifth book bob says hi to the stars


      I know! I can’t imagine it even after over a month.


    I can’t wait 320 days till the release of Blood of Olympus O my gods!!!!!!!!!!!!!!!! I’m already freaking out!!!!!!!!!!!!!!!!!!!!!!!!!!


    Countdown to release: 319 days!!!!!!!!!!!!!!!!!!!!!!! Oct. 7 2014 please come faster!


    From November 25, 316 days till Oct. 7, 2014. Ugh! I can’t wait that long!!!!

  • Sarah

    I think all of them have to be alive to defeat Gaea. All of them have small parts that if they don’t have there doom. Nico surprised me very much but I think he will find love (hopefully not a boy). I love all the books so far. I hope all of them stay alive but the person or thing that dies isn’t one of the seven (I hope). It could me like Luke, the enemy kills himself or someone unexpected like Couch Hedge. Heck it could even be that weird dude Octavian. I don’t now for sure as long as one of those heroes don’t die!!!! BTW Rick don’t care about the other books right now and focuses on the final book! I still have to wait 10 months so right now you are killing me!! PLEASE!!!

    • Percyand Annabeth

      Well it can’t be couch Hedge or an enemy because you Gaea needs a demigod but you got a point with Octavian. Maybe? Don’t you think maybe someone with sacrifice for someone? You also got a point that everyone has a special part and if one dies its going to get pretty hard. I hope nobody dies but you never now with Rick!


    From today, (Dec. 2nd) 309 days. This wait is going to kill me!!!!!!!

    • nicolover 23

      percy lover 1 what is the acuall date for the boo

  • emerson

    the house of hades ws awesome but i’m bummed out i have to wait a year to get the last book remember leo kissing calypos

    • Legendary#1

      I know right!!!!!:)

      • PERCYLOVER#1

        Leo and Calypso were my absolute favorite part of HoH (well that and Annabeth and Percy in Tartarus) but seriously Leo HAS to go back for her and not just because he swore on the river styx. If he doesn’t I will be so mad at Rick.


    We’re almost down to the 200′s. From today, Dec. 5, 305 days.

  • #percylover

    Bob :(


    299 days! That’s way to long Rick is definitely trying to kill us with this wait.

  • Skittles

    Nico is amazing to have kept that secret. Nico di Angelo fan club!!!! Bob says hi to the sun and stars….. You are in my heart forever, Bob.

  • Mica

    I just laughed when I read the part about Nico.


    275 days guys. This is seriously going to freaking kill me.

  • DcFrosting

    i am sooooooooo exicted!!!!!!!!!!!!!!! I miss you bob! Who do you think thats going to die?


    267 days till Oct. 7th and I’m starting to get seriously annoyed at having to wait this long.

  • ZeldaFan09

    I think The Blood of Olympus sounds BLOODY.

  • lol

    dont forget aphrodite hinted that percy and annabeth’s lovewas a tragedy that might have something to do with it. i honestly dont know. rick is killing me here!

  • Johnny

    that sucks

  • Hazel

    I love these books and I can’t wait for the next book!

  • Pizza

    I hate how Nico’s gay… It’s just wrong and gross. Being gay isn’t ok, and it came completely out of nowhere that Nico liked Percy. Much to my dismay, I think the oath to keep in final breath is Percy’s promise to Annabeth about never again separating only because it’s the only oath that wasn’t thought of as the oath. Then again… Idk

    • Clara Harper

      oh look! its a close minded person

  • Doosie

    I just finished the house of hades I can nit wait to read the fifth book and it left me wanting the fifth book really bad


    From Jan. 31st, 249 days. I can’t wait for BoO to come out but at the same time I don’t really want the Heroes of Olympus series to end. You know?

  • Just a Guy

    bob dies… probably he was left behind in tatarus. for those who do not know bob, he was in the demigod files

  • Just a Guy


  • Just a Guy


  • Just a Guy


  • Just a Guy


  • Allison

    I can’t wait until the book comes out



    • CHEESE2



    ok guys first off I love the fact that rick made nico gay first off who cares that its out of the blue it makes the story sooo much more interesting and opens up so much more possibility for what course the story will take and second being gay is not gross. im straight but really guys just because someone like the same gender does not make it “gross”. i totally like the idea of him ending up with Reyna NOT because he’s gay but because i like Percy and Annabeth being together and I feel both he and Reyna deserve something to be happy about in life ! so stop hating on him being gay !!!!!!

  • Danny

    Did anybody see what I did there?

  • annabethchaserocks

    omg i hat the part about nico!!!!!! i have one question Rick… will Percy jackson die?? *whimpers* i hope not lets face it he is really cute

  • Missbrainiac

    Actor for percy is cute in movie

  • Percysgirlfriend

    Finnishd all the books. Rick can you PLEASE make more books. No more gay characters. DISCUSTINGI. NEED to read the new book NOW

  • mysterydude

    I think you guys just spoiled to other people that Nico is gay…
