The Pretty Little Liars summer finale just finished, and we’re already counting down the days until the Halloween special, featuring Adam Lambert! Watch a preview and let us know what you thought of tonight’s episode below!

Pretty Little Liars doesn’t return until Oct. 23 (really — how are we going to survive?!) but thankfully ABC Family has provided us with a sneak peek of the upcoming episode, 3×13 “This Is a Dark Ride.”

In the preview, the Liars are at a Halloween party… on a train. That just spells disaster, doesn’t it? It certainly looks like they’re having fun for once, and we even get our first look at Adam Lambert, who will be performing at the party. This is Pretty Little Liars, so as usual, everything goes to hell, and we see Spencer climbing through train cars, Aria tied up with her mouth taped shut, and Hanna — dressed as Marilyn Monroe — making out with some guy. (So maybe the party isn’t all bad for our favorite four Rosewood gals!)

What do you think of the preview? What did you think of that crazy summer finale? Spill your thoughts and your predictions in the comments below.
