In ancient times, Calypso, sorceress and daughter of the Titan Atlas, lured the Greek hero Odysseus to her home of Ogygia. She kept him captive for seven years before allowing him to return to his wife Penelope. In modern times, she was trapped on the island of Ogygia. There, she was doomed to fall in love with the heroes who found their way there, only to have her heart broken when they were rescued and left her behind. Percy Jackson was one such hero. So was Leo Valdez. But unlike all the other demigods, Leo made good on his promise and returned for his caramel-haired, dark-eyed love. She left willingly despite knowing her departure from the island would cost her her magic powers. Now the two are on a new adventure with Apollo, Festus, and Meg McCaffrey.
