THE TIME IS NOW.

Raised on a foreign world where telepathic wolves hunt in the mountains and mysterious aliens guard against the encroachment of humanity, Nori has grown up scouting in the wilderness. Like her mother before her, she searches for dangers that could devastate the isolated towns scattered across the countryside.

But the wolves have already encountered those forces. Now, disturbed by the sense of death along the broken cliffs of Ariye, they reach out to one who can help them. Unsuspecting, Nori answers the Grey Ones' call-only to find herself mentally bonded to a half-grown, ferocious wolf.

Spies and assassins stalk the scouts and wolfwalkers while a deadly threat, once thought to be contained, spreads across the land. Caught between the wolves and the horror of plague, and with hired hunters at her heels, Nori is hounded deep into the wilderness to begin a journey that must end in victory . . . or death.
