Carlos' Peace (Judgement of the Six Companion #5)

Carlos has spent his entire life avoiding attachments to individuals and has devoted his time to protecting his race. His childhood taught him that something is out there, threatening the existence of werewolves, and he will let nothing interfere with his vendetta to stop the threat.
Physical attachment and vendetta collide when he sees Isabelle. She’s meant to be his Mate and instinct demands that he protect her above all else. However, letting go of his past is as impossible as embracing a future filled with love. Isabelle wants nothing to do with him, except fight with him. Carlos must find a way through her emotional armor and hope, together, they can heal and face the threat.
