Those Who Wish Me Dead by Michael Koryta

If you're in need of a fast-paced mystery thriller, this one is for you.  Jace is just a kid swimming in a pit lake when he sees something he shouldn't have.  Now he's a witness in a murder trial, and people want him dead.  Instead of the typical witness protection program, he's placed into a survival camp for troubled kids in the Rockies.  He likes learning how to survive in the wilderness and it comes in handy when the bad people come after him.  Thanks to the help of a former wildfire fighter struggling with her own demons, Jace is able to confront the people after him and a forest blaze.

Honestly, there were some plot holes and coincidences that I just couldn't forget while reading this one.  I loved the characterization of the Jace though--the elements of a great novel are here, but the coincidences were too much for me.
