Long dreaming of becoming a gryphon rider and training to defend her clan, Roisin Hati is impatient for her sleeping inner wolf to awaken. She never expected a choking cloud of evil magic to do just that. When she finally opens her eyes, a huge black direwolf with stunning cobalt eyes is standing over her—Culgan, son of her beloved godparents.

Culgan freezes when he hears the first snarl of Roisin's rising wolf in his mind, feels her fear in his bones. As a warrior defending the hidden Freki stronghold, bonding has never been a high priority. But something about the white-haired, dark-eyed Roisin rouses an irresistible drive to: Claim. Mate. Possess.

As Roisin navigates battle training, Culgan is at her side, guiding every step. The pull between them grows stronger until it ignites in a glorious mating union. But dark forces are gathering in the desert. A daemon hungry for revenge bargains with a goddess for the power to destroy the Freki. And the gryphon riders may have to make the ultimate sacrifice to save the kingdom.
