The Heroes of Olympus

The Heroes of Olympus is a collection of five novels by American author Rick Riordan, scheduled to be completed in 2014.Riordan drew inspiration from Padraic Colum's The Golden Fleece and The Heroes Who Lived Before Achilles.The series chronicles the adventures of seven demigods as they race against time to prevent the awakening of the earth goddess, Gaea. The first novel, The Lost Hero, continues the story from The Last Olympian, which is the last novel of the preceding series, Percy Jackson & the Olympians. Percy Jackson & the Olympians is a series on the succeeding Gigantomachy of Greek mythology. A prophecy given in The Last Olympian outlines the events of The Heroes of Olympus. Demigods, living secretly in the modern era, are featured in both series. The Heroes of Olympus introduces Roman demigods: children produced by the Roman gods, who are separated from their Greek counterparts. These two groups of demigods are enemies due to a stolen statue of Athena and have been forced apart for centuries, but must unite to stop the main antagonist in the series, Gaea, from gaining control of the earth. Percy Jackson, the protagonist of the previous series, is again the main character.
