The Earth Transformed - Ghost Book I
by Mike Stackpole
Hunting for the source of the killer robots terrorizing the Arizona wastes, a team of Desert Rangers stumbles into the town of Darwin's Village. One of them, Ghost, is also looking for other answers. Only days before he awoke in a cloning chamber knowing nothing of his previous life except that he'd worn a ranger's star and he'd died in Darwin's Village. But who killed him? And why?
