Scarlet by Jordan Summers
Thrust into a world she never knew existed, Gina Santiago does her best to fit in with the others while coming to grips with the fact that she's a werewolf. The transition isn't easy, especially since her boyfriend, Morgan Hunter, is an alpha werewolf - and her new boss. Unfortunately, someone doesn't want Gina and Morgan to succeed at recruiting Others for a rival tactical team. The enemy will do whatever it takes to prevent a team from forming, even if that means killing off the new recruits and trying to tear them apart. Now along with trying to hold their crumbling relationship together, Gina and Morgan must stop the killer before he strikes again. And there's that little problem of a blood war looming on the horizon.
