Lois Peterson would like a nap, but she's not going to get one any time soon. She hasn't even recovered from her last encounter with the world of mythology when Odin shows up on her doorstep, seeking help. Of course she wants nothing to do with him, but circumstances conspire to force her into confronting a conspiracy that's going to get her killed if she's not careful—and if she can't stop it in time, the consequences will be disastrous for everyone around her. And if that's not enough trouble, the animal-weres she loves even when they are extremely irritating are losing control over their powers of shifting, and the only way to help them is to do what she's always sworn she'll never do: unite her magical powers with a demon's. Through the challenges of grief, love, and letting go, Lois finally learns what it really means to be the most powerful wizard on the West Coast.
