Pure by Julianna Baggott

Partridge lives in the Dome. His life is perfectly structured; every minute of every day dictated. He doesn't know much about life outside of the Dome, except that the beings that exist there are wretches, fused with the things around them when the detonations occurred. Partridge believes that his mother is out there, among the wretches, and decides to escape the Dome.
Pressia is one of the wretches. One of her hands is fused to the doll's head that she was holding when the detonations happened. As her 16th birthday approaches, she knows that she must turn herself in to either become part of the militia or a live target for them to use for practice.
Both on the run, their paths cross, and the future will be forever changed.

While I enjoyed this book, I found it somewhat predictable. It was definitely a different kind of story than I typically read; lots of war-like situations, very disturbing imagery of a world after nuclear detonations. The storyline was exciting, though, so it kept me reading. Waiting for Fuse to come later this month.
