After the stunning twist at the end of book 1, SURVIVOR, Jesse finds himself truly alone. The military personnel he meets are guarded - but it seems likely that safety lies just outside the battered city. When Jesse meets three very different fellow teens, he is offered a badly-needed sense of community. But will Felicity, Jesse and Rachel help him escape and return home, or will he be trapped indefinitely - and always within reach of the merciless, contaminated Chasers?
