Away We Go by Emil Ostrovski
"Westing is not your typical school. For starters, you have to have one very important quality in order to be admitted—you have to be dying. Every student at Westing has been diagnosed with PPV, or the Peter Pan Virus, and no one is expected to live to graduation. What do you do when you go to a high school where no one has a future or any clue how to find meaning in their remaining days?"- summary from Amazon
Really interesting, smart, emotional book. I also really liked the gay MC angle, which I didn't know about when I first started the book so it was a nice surprise.
