In the house of Helios, god of the sun and mightiest of the Titans, a daughter is born. But Circe is a strange child who possesses the power of witchcraft, which can transform rivals into monsters and menace the gods themselves. Threatened, Zeus banishes her to a deserted island, where she hones her occult craft, tames wild beasts and crosses paths with many of the most famous figures in all of mythology. But there is danger, too, for a woman who stands alone, and Circe unwittingly draws the wrath of both men and gods, ultimately finding herself pitted against one of the most terrifying and vengeful of the Olympians.
