I read The Compound by S.A. Bodeen and it was one of the best books I have ever read. It's about a boy who's family lives underground due to a attack of nuclear bombs. He thinks he's one of the few who survived the attack, but he discovers that a ton of what he thinks is true is definitely not.
This book has mystery and lots of action. It has a futuristic setting, and (I think) a great conflict. It keeps you guessing what's going to happen next. It's one of those books that you just can't set down. I would totally give it a ten.
