Hades' Daughter is the first novel in the Troy Game series.  Millennia ago, during the late Bronze Age, the king of Athens was forced to send seven youths and seven maidens to Crete every nine years.  There they were left in the dark maze of the Labyrinth to become victims of Asterion, the Minotaur son of the Minoan king.  One year, the Athenian king sent Theseus, his own son, to Crete among the sacrificial levy.  Theseus gained the love of the Minoan king's daughter, Ariadne, slayed Asterion and escaped with the other captives, Ariadne, and her younger sister Phaedra.
