Cassie Palmer, once a down on her luck clairvoyant and currently the chief seer of the supernatural world, is in the fight of her life. While on a rescue mission to Faerie, she is kidnapped by Aeslinn, a king of the light fey. He is her sworn enemy and has every reason to want to kill her, yet instead he offers a trade: her life for that of her lover, John Pritkin.

Cassie doesn't know what the king's game is, only that it involves his alliance with Zeus, the head of the ancient pantheon who used to rule Earth and who is determined to do so again. In order to save her lover and the world, she has to figure out what Zeus and his royal puppet are up to. She also has to stop them, even if it means taking on the king of the gods himself.
