Four clans have been at war for centuries: the Kodiak, the Raven, the Wolf, and the Ram. Through brutal war tactics, the Ram have dominated the region, inflicting death and destruction on their neighbors. Seventeen-year-old Zo is a Wolf and a healer who volunteers to infiltrate the Ram as a spy on behalf of the allied clans. She offers herself as a Ram slave, joining the people who are called the Nameless. Hers is a suicide mission - Zo's despair after losing her parents in a Ram raid has left her seeking both revenge and an end to her own misery.

Striker Gryphon has lost his position of honor among the Ram and is now a hunted man, a traitor. Zo, the object of his affection, was murdered by members of his former clan. To honor her memory, he journeys to the highly secretive Raven Nest to warn strangers of their impending demise - even though it could cost him more than just his pride.

Gryphon has 23 days to ensure that Zo, Joshua, and Tess are cared for before offering his life as a ransom to Chief Barnabas in exchange for the lives of his best friend and mess brothers. He doesn’t have the nerve to break Zo’s heart with the truth, and he spends his time inside the Allied Camp trying not to despise the very people he’s been raised to hate - the Wolves. But Gryphon is not the only one harboring secrets.
