I Hunt Killers by Barry Lyga

Barry Lyga chooses topics for his books that few authors would think of for YA books. (Think Boy Toy). In I hunt Killers, Jazz is the son of serial killer Billy Dent, a sociopath who did his best to involve his son in what he thought of as a family vocation.  He is in prison now, but there is a new killer in town and Jazz wants to stop him.

Unwind by Neal Shusterman

What a provocative story.  Full of danger, adventure and unforgettable characters.  At the end I wondered how many of us, particularly between the ages of 13 and 18, could convince a jury that we are more important than the sum of our parts.
