Leo Valdez's device with the crystal from ogygia fails, and he is unable to find Calypso. He returns to camp dejectedly, and everyone's elated to find him alive, but also that he is very depressed. In vain, he tries everything he can to find Ogygia. But Calypso's words repeat themselves over and over:
"No man has ever found Ogygia twice"
He is angry.
Meanwhile, Percy Jackson sees how Leo is and feels that it's his fault that Calypso is not freed. He is determined to help Calypso, and on the quest to find her, he discovers things about himself, that he couldn't even imagine surface.
Can anyone free Calypso?
