When Lilith Bennett is invited to Crete for a Future Leaders Conference, she has no idea what s really in store for her. She finds herself struggling through a series of tests created by the Daughters of Ariadne, a secret sisterhood sworn to guard the ancient Greek Labyrinth and all it contains, and discovers that her mother, killed the year before, has ties to the sisterhood. The Daughters test the physical, mental, and emotional strength of Lil and her friends, but when three members of the Zephylites, an order devoted to the adoration of Zeus, break into the Labyrinth, Lil must decide whether to risk her life and the lives of her friends to protect all the Daughters hold sacred.
