Three, very different, and I'm glad I read all of them. Flash Burnout, What I Saw and How I Lied, Nothing.
Flash Burnout: Read this if you're after the boy voice.
What I Saw...: Seemless mixing of 'historical' elements in a timeless 'first love' story. With complications.
Nothing: Think Lord of the Flies and then think again. Incredible voice. From the writer's point of view, this shows incredible restraint/control.
