Love or life. Henry or a child. Lose your family or let the world end? The choice is Kate's. She survived nine months of imprisonment, faced an intolerant goddess and a vengeful titan. And now Calliope has claimed her rights to the unborn child. Kate is unable to stop her, but Kronos unexpectedly offers to make a deal. If Kate shows loyalty and devotion to the king of the titans, he will spare humanity, but still kill Henry, her mother and the rest of the Council. If Kate refuses, then Kronos will tear the whole world apart, and every single one will die. Now the fate of everyone who is dear to Kate rests on her shoulders, and the girl must do the impossible: kill the most powerful creature at any cost. Even at the cost of her own life.
