Artemis Fowl: The Opal Deception by Eoin Colfer (Author)

Artemis The Opal Deception, 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 The Eternity Code and followed by Artemis 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. There is a secret code at the bottom edges of the text, containing a message from Foaly. This is translatable if one has the Gnommish alphabet, available in The Artemis Fowl Files by Eoin Colfer, or the Artemis Fowl website. The message on the cover of the US publication, barely decipherable, reads "Opal wants revenge", it is faintly repeated several times on the sides of the tube. The Gnommish symbols around the molecules on the front cover read "DNA never lies". (Wikipedia) ABOUT THE Eoin Colfer (born 1965) is an Irish author of children's books.
