After fighting in the Trojan War against her own people, Daphne is plagued by memories—of her family, of her shortcomings, of her lover, Apollo, and of the secrets he and the gods keep. As she reels from the horrendous sacrifice she had to make and her own failure in the battle for Troy, she knows the Titans are out there—just beyond the island of Aeaea where she has taken refuge—raging a war against the world.

As Daphne struggles to regain her will to fight as well as rein in the new abilities that have been thrust upon her, the gods call for her help once more. But it has been prophesized that she will bring about the ruin of Olympus and the downfall of Sparta, just as she caused the destruction of Troy. Now, as she begins to witness her terrible destiny coming true, she must become a hero to rival those of myth and save the gods, her people, and the world. Or she will watch it all burn around her.
