Heller High senior Paul Baum—aka Paulie Bomb—tells the truth. Not the "Wow, that's an ugly sweater" variety of truth, but the other kind. The truth that matters. It might be hard. It often hurts. But Paulie doesn't know how not to tell it. When he tells his girlfriend Hannah the life-altering, messed-up, awful truth, his life falls apart. The truth can get complicated, fast.

But someone in Period 8 is lying. And Paulie, Hannah, and just about everyone else who stops by the safe haven of the P-8 room daily are deceived. And when a classmate goes missing and the mystery of her disappearance seeps beyond P-8 and into every hour of the day, all hell breaks loose.
