One last chance. One wild weekend. Flat out the funniest book of the year.

My name is Caitlin, and up until 48 hours ago, I had never: tasted alcohol, kissed a boy, sang in public at the top of my lungs, kidnapped anyone, or - what? Stolen a convertible? Now I'm in jail, and I have no idea what I'm going to tell: the police, my parents, the mayor, all of those camera crews, and everyone on Twitter. I have just noticed that: my nose is pierced, and I have - wait? Is that a tattoo? I blame one person for this entire insane weekend: my famous cousin. Who is also my former best friend. Who I have hated for the past four years. Who I miss like crazy. No I don't! It's all your fault, Heller Harrigan!
