Anne Rice's sister wrote this and is also good at getting you interested in reading what happens to the characters she creates, the difference being this is about werewolf types as opposed to vampires in Rice's books.
A real page turner! The story starts shortly after Regeane's and Maniel's wedding. Aiding King Charles in his takeover of Italy from the evil Lombard King, Maniel and Regeane face one danger after another. Using their shape-shifting abilities they experience some harrowing adventures, including dealing with a "bear" spirit who can possess and inhabit human bodies at will. Non-stop action and hard to put down!
