Fittingly, Pottermore has announced that the last Harry Potter and the Chamber of Secrets chapters will open tomorrow, October 31.

The specific opening time is 12 PM GMT/8 AM ET/5 AM PT. We had learned exactly a week ago that the final chapters were due out this month, but an exact release date hadn’t been set. Due to some of J.K. Rowling’s new material leaking early, we know that new writing from our favorite author will be about The Sword of Gryffindor, Ghosts, and the Chamber of Secrets.

We expect a mini game or two, and fun new items to “collect” as well!

We’ll have a detailed post of what’s new and most interesting, like we did for the last release of chapters in September. Chapters five through eleven of Chamber of Secrets included new information on King’s Cross Station, Pure-Bloods, Peeves, Hogwarts ghosts, and Draco Malfoy. Two new games were introduced. In one, you had to get the pixies in Lockhart’s office back in their cage in a certain amount of time. In another, you had to brew a potion a particular way (using ingredients you already had), then return to Professor Snape’s office in a previous chapter to unlock a surprise.
