No Mercy - Sherrilyn Kenyon

Shape-shifter Dev Peltier thought he knew it all. But one night when a Dark-Hunter, who is also an official member of the Dogs of War, sashays into his bar, Dev realizes he might have met his match. Martin's Press. \n \nLive fast, fight hard--and if you have to die, take as many of your enemies with you as you can. That is the Amazon credo and it was one Samia lived and died by. But today, in contemporary New Orleans, the immortal Amazon warrior is about to learn that there's a worse evil coming to slaughter mankind than she ever could have imagined. \n \nMeet Dev Peltier. A shapeshifter who has stood guard at the front of Sanctuary for almost two hundred years, he's seen it all--or so he thought.

But in order to win, they will have to break the most cardinal of all rules--and pray it doesn't unravel the universe as we know it...\n
