Prison of Solitude — Jason D. Morrow

Skylar and Liam have escaped Vulture Hill, but they are not free yet. The gates to the Containment Zone are still closed and getting out will be their biggest challenge yet.

First, they must travel to their home where Liam has hidden the cure for the greyskin virus. Then they must find a way out of the Containment Zone. But they know they can't do it alone.

To reach their destination, Liam must enlist the help of bandits and is forced to trust a man who wants him dead: Carver. With Screven soldiers on their trail and the threat of betrayal at every turn, Skylar and Liam can't afford to fail. The fate of the world depends on their survival.
