This is a most satisfying and creative teen sci-fi book. I LOVED it! It didn't get too too teen-y, it was wonderfully setup with multiple points of view. The layout and storytelling almost turned it into an episode of Battlestar Galactica in my head (a definite bonus). Actually, that's not a bad comparison. I would also liken it to another great sci-fi teen series, "Across the Universe" by Beth Revis. It's a pretty quick read despite its size, and while the cursing is blanked out, it does have some cursing and pretty intense action.
