DeWitt's Pack, book 09 : Taken by the Alpha Wolf
Marcy Jacks

After being separated by death for over a thousand years, alpha werewolf Blasius has found his mate, reincarnated into the body of Detective Ryan Miller.

Ryan was injured in the last battle between hunters and werewolves, and Blasius has no choice but to force him out of his human life and turn him into a werewolf to keep death from separating them once more.

As a new werewolf, living by the laws of the pack is entirely different from the laws of a human, and Ryan doesn't know if he can adjust to this new way of life.

Blasius must convince Ryan, a down-to-earth man, that his place is at Blasius's side with the rest of the pack, before a new group of hunters arrives to finish what they started.
