A thousand miles of wilderness. Innumerable dangers. Uneasy alliances. A bond forged in blood. The odds are great, and survival has never been more uncertain.

Vampires and humans have always been bitter enemies, destined to push each other to extinction. But when a group of scientists develops a genetic enhancement meant to boost the effectiveness of human hunters, tragic results threaten to bring about the destruction of vampires and humans alike.

After the fallout of Year Zero and rise of mutated hybrids known as morphs, the remaining humans retreat into five fortresses. All seems well until Easthaven is attacked in an assault that leaves only thirty survivors. Enter Marcus Warren, one of the most powerful hunters in existence. Reluctantly, Marcus assumes leadership and decides that the group’s only chance of survival is to cross a thousand miles of wilderness to Ashland.

Forced to trust a hybrid named Clio and a vampire called Aya, Marcus and the others set out. Dangers lurk everywhere, and enemies seem destined to destroy them…if they don’t destroy each other first.
