Ariadne is destined to become a goddess of the moon. She leads a lonely life, filled with hours of rigorous training by stern priestesses. Her former friends no longer dare to look at her, much less speak to her. All that she has left are her mother and her beloved, misshapen brother Asterion, who must be held captive below the palace for his own safety.

So when a ship arrives one spring day, bearing a tribute of slaves from Athens, Ariadne sneaks out to meet it. These newcomers don't know the ways of Krete; perhaps they won't be afraid of a girl who will someday be a powerful goddess. And indeed she meets Theseus, the son of the king of Athens. Ariadne finds herself drawn to the newcomer, and soon they form a friendship--one that could perhaps become something more.

Yet Theseus is doomed to die as an offering to the Minotaur, that monster beneath the palace--unless he can kill the beast first. And that "monster" is Ariadne's brother . . .
