Ten years after the war with Gaea, Leo and Calypso decided to take a break from Camp Half Blood in winter so they could visit Hazel and Frank and go back to Hazel's old apartment in Alaska so they could learn more about Sammy Valdez. Two years ago, Calypso gave birth to a beautiful baby, which Leo have convinced (fire was involved)Calypso to name her Esperanza instead of whatever-that-name-was that Calypso wanted to name their daughter.Esperanza Valdez has Calypso's beautiful almond eyes, honey-blond curly hair and she has Leo's mischievous smile and a talkative personality.
After saying goodbye to their friends in Camp Half Blood, they got into the car which Leo had found in an abandoned garage. After a few weeks, the car looked as new as the ones in Ford.
After they passed the Canada border through the Niagara Falls, they stopped for a gas station. Esperanza had been sleeping so quietly that both of them haven't looked at the back of the car for a few hours."Stay in the car.I will be back." Leo said and he kissed Calypso on her cheek. Then he put on his coat and left the car to pump the gas. Then Calypso turn her head around to check on Esperanza, but she only found an empty children car seat.
