Jeremiah — Jessica Cage

After leaving his home, tired of living in the shadow of a brother who hadn't known he existed, Jeremiah's life took an unusual path. A rogue wolf, he found himself part of a new pack, a team of elite mutated wolves fighting off all the things that go bump in the night. Science and magic combined to turn his wolf into an entirely new beast. Life was good, his wolf could run free whenever he pleased, and women flocked to him. 
Unfortunately, all good things must come to an end. When one of their targets escapes and injures his brother, Jeremiah is faced with a difficult decision. Stay in line and let his brother die, or defy his orders and try to save the only family he has left. Through a fortunate coincidence his journey home reconnected him with a lost love; but even she has her secrets...

Demons never stay hidden for long...
