The ascension to the throne of Ragnar, the bastard son of King Balthazar, has created chaos and despair in the Kingdom of Thalia. Young Duke James Beckwith cannot allow Ragnar to end his family's legacy, one of the most prominent in the kingdom since the times of King Ishmael. To defeat Ragnar, James sets out on a quest to find the Stone of Hades, a magical relic that will save the kingdom and restore its splendor and wealth. But to activate the powers of the stone, James will need the help of Aurora, a Siren, the natural enemy of man. James must put aside his prejudices, pride and, most difficult of all, his feelings for Aurora to save his family from ruin and dethrone, once and for all, Ragnar of Milos.
