The Bone Throne

Princess Seraphina, a necromancer forced to execute werewolves in brutal public spectacles, accidentally binds her life to Alpha Konstantin when her resurrection magic works perfectly on him for the first time. Death-bound as fated mates, they're kidnapped together by his pack—where Sera discovers her "cursed" magic is actually sacred, and that her father has been harvesting werewolf bones for immortality. Trapped between the humanity that reviled her and the monsters who worship her, Sera must choose which world deserves her loyalty—and whether she can forgive herself for the blood already on her hands.
