It's Kind of a Funny Story, by Ned Vizzini
Like many ambitious New York City teenagers, Craig Gilner sees entry into Manhattan's Executive Pre-Professional High School as the ticket to his future.
Determined to succeed at life—which means getting into the right high school to get into the right college to get the right job—Craig studies night and day to ace the entrance exam, and does. That's when things start to get crazy. At his new school, Craig realizes that he isn't brilliant compared to the other kids; he's just average, and maybe not even that. He soon sees his once-perfect future crumbling away.
Vizzini "clearly has not lost his knack for conveying the textures of teenage life," in this book about a boy's slip into mental instability. - Publishers Weekly
