Blood Wolf: Wereling Book #3 (Wereling, 3)

Trey Laporte had been told he was the only one. It was a lie. But some secrets he would have been better off not knowing. Trey, the last hereditary werewolf, has found his pack – and they're vicious, bloodthirsty, and truly wild. All Trey wants is to go home, but having learned more about his Wolfen nature, he has decided, for the safety of his friends, to never return.

Back in London, Alexis uses her magic to track down the Necrotroph that is intent on infiltrating her father, Lucien's, organization. But while Alexis is focused on the outside threat, Lucien is battling with his own darkness. His evil brother Caliban's savage bite and the poison left behind have reawakened Lucien's vampire instincts – turning every night into a battle.
