Leo: "How do I calm Calypso down? I can't blame her. Riding a dragon is not a good way to spend six months."
Apollo: "We have to locate and fight a half-immortal Roman emperor. We don't even know his name or what he looks like."
Emmie: "My daughter, Georgina, and countless others have been disappearing. I rescued you because I just knew you had been sent by the gods to help us."
"Stop complaining and think!"
"I have to rescue these Griffins, find clues about the emperor, and not get caught in the process? I have to do all of this with nobody but Calypso?"
In the summer of 2011, we find our main characters Apollo, Calypso,Leo in Indianapolis, Indiana far from home. They are rescued by an elderly woman named Emmie, who brings them into her home.
"Pessimistic and annoying as always."
Meg: "Ready for another ridiculous mission?"
People in Indianapolis are inexplicably disappearing. Our teen trio of the god Apollo, Leo the demigod and Calypso the titaness are called upon to come to the rescue. In addition, the teen trio must stop the emperor from taking over and destroy the oracle of Trophonius if they can find it.
"I'm afraid not. He's made himself half-immortal. He probably fled."
"He has to be after that fall."
"You think he's dead?"
Apollo and Calypso find themselves in a secret section of the Indianapolis Zoo searching for two Griffins that disappeared from their owners' home (courtesy of the crazy net goddess, Britomartis), and to obtain clues that might help them find the Roman emperor who is believed to be responsible for the disappearances. They are rescued by Apollo's former companion, Meg, after they are pursued by the emperor's men.
Grover: "How did I get here?"
"I am so happy to have my little girl back home and safe."
Apollo and Calypso, along with Apollo's long lost companion Meg, infiltrate the emperor's hiding place. The emperor is now identified as Commodus. The three receive help from a large group of female archers and rescue the missing people, returning them home. They also swiped the throne of memory on their way out. Apollo and Meg leave Calypso behind and go to the cave of Trophonius and destroy the oracle and return to Emmie's house with an only half-sane Meg.
Commodus has broken into Emmie's home and his former victims, Emmie, Leo, and Calypso are fighting him. Apollo is able to summon a surge of his old godly power to reveal his true godly form and blind Commodus, who falls out the second-floor window.
Although Commodus survived his fall and fled, Emmie and her daughter are safe again. Meg's sanity is restored and with that, a prophecy is spoken. This leads to their next adventure. Leo and Calypso leave to warn some allies in California of an attack. Apollo, Meg, and a new companion, Grover leave for the Southwest United States to find the next emperor that they must defeat.
