The Hunter's Omega Mate: DeWitt's Pack, Book 2 (Unabridged‪)‬

When Tristan Scott ran away from his pack to avoid the roving eye of a cruel alpha, he never expected to save the life of Isaac Foster as he was drowning in the river, nor did he think the gorgeous man with purple eyes would be his mate, or a hunter of werewolves. Isaac has hunted werewolves ever since watching his family being murdered as a kid. He hasn't had time for relationships, but there's something about Tristan he can't get enough of. Their easy time together is shattered when they're attacked and Tristan is forced to transform to defend them. Isaac cannot believe it, and threatens to kill Tristan should the two ever meet again. But meet they do. They cannot separate themselves from each other, regardless of their enemy status, and soon they must decide whether or not a hunter really can love a werewolf without it jeopardizing both of their lives.
