Bite the Bullet (Crimson Moon, Book 2)

Used - Sasha Trudeau considers herself a soldier first and a werewolf second. But while her secret government-sanctioned task-force faces its greatest challenge so far, Sasha faces something much more primal: the undeniable pull of the moon―and her own desires.

With rogue wolves savaging both the human and paranormal worlds, Sasha's team of elite operatives has one job: destroy the rogues and isolate the deadly toxin that's poisoned their blood. But the challenge is far more complicated than Sasha could have imagined. Soon she is thrust into a full-scale supernatural war for supremacy―and the only man left who Sasha can turn to might be the biggest danger to her of all. . .and in more ways than one.
