Fat Kid Rules the World - K.L. Going

How this book won a Printz award is beyond me.  It was poorly written and I guessed the ending after 20 pages.  Troy Billings is a fat kid who wants to commit suicide by jumping in front of a train because apparently at 6'1" and 300 pounds he's too fat to do anything.  Curt is a semi-homeless, skinny drug addict guitar god kid who sees Troy in the subway and saves his life.  Naturally these 2 become friends and Curt wants Troy to play drums in a punk band.  The rest of the book is filled with unrealistic fat kid stereotypes and constant mentions of said fatness.
