Percy Jackson & the Olympians is a series of adventure and fantasy books authored by Rick Riordan. Set in the United States, the books are prominently based on Greek mythology. The series consists of five books, as well as spin-off titles such as The Demigod Files and Demigods and Monsters. The Lightning Thief, the first book, is the basis of a film called Percy Jackson & the Olympians: The Lightning Thief, which is scheduled for release in the United States on February 12, 2010.
The protagonist is Percy Jackson, who discovers that he is the son of Poseidon, god of the sea and earthquakes. He learns that the legendary beings of Greek mythology still exist and have always existed, including monsters, cyclopes, empousai, Titans, and also the Olympians (Greek gods) themselves who dwell in Olympus which is now situated at the mythical 600th floor of the Empire State Building. He is frequently attacked by monsters because he is a child of one of the "Big Three" (Zeus, Poseidon, and Hades). Percy meets many other young demigods, both friendly and hostile, who are also in the process of discovering their heritage and powers.
The series stayed on the New York Times Best Seller list for children's books for 129 weeks as of January 6, 2010.
