Icebound Oath The Forgotten King

In a Gothic frozen fantasy world, werewolf Alpha Nolan and vampire heir Ethan are bound by an ancient blood oath with sealed memories. Reunited in an ice temple, they turn from rivals into allies, expose regent Silas's plot to massacre royals and stir clan strife, break the mind-wipe seal, end centuries of conflict, and establish a co-ruling regime for wolves and vampires.
