Mitch McCaffrey and Diana Corcoran Winstead are about to be married when Mitch receives a surprise visit from Alyssa McCormick, a mysterious beauty who is being pursued by…a werewolf. After a harrowing encounter with the warg, Alyssa identifies herself as the grand-niece of Mitch’s late mentor, Dr. James McCormick, and asks for Mitch’s help. She says the werewolf was sent by the CIA, whose agents are convinced she possesses a spying spell. She says she does not, but believes the spell is in the books Dr. McCormick bequeathed Mitch. To make it worse, she says the FBI wants the same spell, and she thinks the Bureau will trump up criminal charges against her to get it.
Alyssa wants to borrow Mitch’s grimoires. And she wants him and Diana to find a lawyer for her. Mitch and Diana are reluctantly drawn into a game of cat-and-mouse, both magical and legal. But they have little choice, since the government now knows about them, and they are at risk, too. Mitch and Diana turn once again to Kathryn Turner, who brings in a new associate, Ben Callahan, to assist her and Marc Washington fend off criminal charges, while Mitch, Diana and Alyssa walk the pathways of magic to face down paranormal threats. One of these is their old nemesis, Monica Gilbert, who resurfaces as a consultant for the FBI.
But where will the pathways take them? To prison? Or worse?
