Wild Hunts — Rhea Regale

As a revered white wolf, Kasa Jones is well aware of the dangers stalking her. She and her brother, Jordan, track down holding cells and free innocent werewolves before they're reprogrammed to kill her. The night Kasa botches a hunt, exposing herself to the enemy, she flees for her life and lands in the claws of two mysterious wolves. Micah and Slade Castrove have been hot on Kasa's trail for months. With her finally in their care, the brothers vow to protect her from the dangerous rebels hungry for white wolf blood. They never imagined the challenges that would come with keeping Kasa safe. Kasa is enraptured by her mates. Their body-heating good looks, powerful personas, and promises of protection easily sway her priorities. But when her brother is kidnapped and the only way to save him is to sacrifice herself, can her mates protect her from the ultimate hunt?
