Book Description
Picking up where the first book left off, Will, Chester and Cal are on the Miners’ Train and headed for one of the most dangerous places imaginable … The Deeps. Here they face terrors worse even than those in the Colony; vicious renegades who will kill you just for your boots, savage creatures long thought extinct, and Styx soldiers who roam the dark wilds slaughtering anyone who gets in their way. And as if that wasn’t enough, Will learns that Rebecca is embarking on an evil plan that threatens every single person on the planet.
