Abandoned and friendless, Layla accidentally meets the exiled werewolf Fenrir. Instead of hurting her, he quietly stands guard over her. The two huddle together in a forest cave, gradually building trust and a deep bond. When the tribe's patrol raids them, Fenrir fights a bloody battle to protect her. On the night of the full moon his bloodline spirals out of control—but Layla soothes him with gentle tenderness. When the clan chief leads a great force to corner them, Fenrir bites down on his own mark and forges an eternal bond with her, determined to guard her with his very life as they face the tribe's pursuers together.
