Riley left home with her friends and her brother. Now she s the only one left. But in the radioactive Outlands, Riley is far from alone. A psychopath named Little Red hunts Riley with a team of killers. Bear s Army, led by the volatile, sickle-wielding Tris may or may not offer her protection. The backwoodsman Cosmo and his brood of misbegotten mutant offspring haunt the Outlands. And stalking them all is an enigmatic monster that will not be stopped. 

The final confrontation between humans, mutants and zombies looms. But it s only when the battle is over that the real chase begins. Terror has been awakened. It knows no rules. It accepts no bounds. It will pursue Riley to her end. Or its own.
