Oskan and Thirrin thought their bad-seed daughter was gone for good — burnt to a cinder and cast out onto the Spirit Plain. But banishment did not kill Medea; it made her stronger. Now, allied with Cronus, embodiment of all evil, the young sorceress is plotting revenge. Thirrin is distracted by a new invader whose troops ride huge triceratops-like beasts into battle. But the warlock Oskan realizes the true threat to the kingdom is the demon army assembled by his daughter. To ensure the Icemark´s eternal safety, he knows he must destroy her soul — even if it means sacrificing his own.
