Phoenix Island was a good read--I think pre-teen boys would probably find it to be a page-turner. Carl, a fighter and down-on-his-luck kid with noble intentions, gets sent to a sort of isolated juvie. He plans to keep his head down til he gets out but notices more and more strange things happening, possible medical experiments on the inmates, and sadistic drill-sargeant-like leaders. Carl is respected for his fighting skills and gets selected for an elite group within the camp, but when he figures out what's really going on, he must find a way to escape--and to save the friends he's made along the way.
This one seems ripe for a sequel, so keep an eye out!
