Soul Magic by Macy Blake

Blood runs soul-deep, but found families are forever.
Cormac hasn’t been the same since the night the High Moon Pack was attacked. With his magic weakened, he’s consumed by a bloodlust he hasn’t felt since he first became a vampire. His need to replenish his power makes him a danger to his last remaining family member, and his hunger makes him careless. Feeding from pack beta Liam Benson was supposed to slake his appetite, not leave him craving more.
Liam is drawn to Cormac in ways he can’t explain and as the fight to protect the pack he loves reaches a critical point, his connection to Cormac deepens in a way neither wolf nor vampire anticipated. Will Cormac’s role in the final showdown against the dark forces threatening the pack sever the bond Liam and Cormac have started to weave?
Simon, Gray, and Cormac must fight a being history says shouldn’t exist—one with all three types of magic. The pack must use all their resources to combat the mysterious triad, even turning to the mysterious Conclave of Mages for help. As they learn more about this terrifying dark threat, protecting the pack proves to be riddled with challenges and sacrifices. While Gray attempts to hold his traumatized pack together, Cormac struggles to reconcile his past failures with his current desires, and Simon must attempt the impossible: an alliance between mind, body, and soul.
