The truth has been revealed. The Battle for Atlantis has begun. Corinna has returned home. But Atlantis is not the same as it was when she left it… Ilias, her once betrothed, has seized the throne from his uncle the king. Each moment that passes, he loses more and more of himself to the God of War that rests within him. Jace has returned to offer his support, risking his own life to protect hers. With the city burning around them as Ilias becomes more violent and reckless, Corinna discovers the extent of her own power—and struggles to control it. With her friends and Jace at her side, Corinna must come to terms with her own fate, and her own power, in order to save the city that she loves— even to save Olympus itself.
