Artemis Fowl: The Opal Deception (known as Artemis Fowl and the Opal Deception in Europe) is a teen fantasy novel published in 2005, the 4th book in the Artemis Fowl series by the Irish author Eoin Colfer. Preceded by Artemis Fowl: The Eternity Code and followed by Artemis Fowl: The Lost Colony, it is centred on the brilliant pixie Opal Koboi's second try at rebellion (after her first attempt was a failure) and Artemis Fowl II and his fairy comrades' efforts to stop her. Critical reception was mixed, with some reviews praising the book but others pointing out confusion and poor writing.
