Wolf's Fall - J. D. Tyler

A top secret team of wolf shifters, the Alpha Pack are former Navy SEALS that use their Psy powers to take on the world's greatest predators. But while each member is loyal to the pack, it can be hard to deny the call of desire.

Still tormented by his recent captivity, Alpha Pack commander Nick Westfall isn't sure he's fit to lead—especially when he meets the one woman he can't claim without reliving the torture he endured at the hands of a rogue vampire.

Vampire princess Calla Shaw has seen her own share of heartbreak, but she can tell that the wild attraction she and Nick feel for each other could turn into something significant—if only he'd let it. But Calla isn't about to give up on her mate without a fight.

Time is running out, not only for Nick to claim his mate, but for Calla and her coven. A vampire war is on the horizon, one the Alpha Pack can't hope to win if their leader can't pull himself back from the abyss.
