Four Girls, One Island, No Second Chances. The story is set in 3,500 BC and portrays the Titans as a band of fair-haired marauders who have taken over a mythical island named Helios where they have built a stronghold on Mt. Olympus. In order to earn a seat on the ruling council, their children must undergo a survival challenge on a deserted outer island. On Mythikas they will learn their strengths and weaknesses and face their greatest fears. In Book One, the story begins when sixteen-year-old Diana is denied the leadership position in favor of her nemesis and half-sister Athena. Their rivalry heats up as they are left alone with cousins Persephone, granddaughter of a mystic Heliot healer, and Aphrodite, pampered daughter of Poseidon. Diana fights for control of the group once they land but soon realizes nothing is what it seems. She is determined to prove she is a hero, or die trying.
