Twelve-year-old Artemis is a millionaire, a genius-and above all, a criminal mastermind. But Artemis doesn't know what he's taken on when he kidnaps a fairy, Captain Holly Short of the Leprecon Unit. These aren't the fairies of the bedtime stories-they're dangerous!

Artemis is at boarding school in Ireland when he suddenly receives an urgent video-email from Russia. In it is a plea from a man who has been kidnapped by the Russian Mafiya: his father. As Artemis rushes to the rescue, he is stopped by captain Holly Short of the Leprecon fairy police. But this time, instead of battling the fairies, he is going to have to join forces with them if he wants to save one of the few people in the world he loves.

Details the third thrilling adventure of resourceful young criminal mastermind, Artemis Fowl, who has found a way to construct a supercomputer from stolen fairy technology.

Ten thousand years ago, humans and fairies fought a great battle for the magical island of Ireland. When it became clear to the fairy families that they could never win, they decided to move their civilization underground and keep themselves hidden from the humans. All the fairy families agreed on this, except the 8th family, the demons. The demons planned to lift their small island out of time until they had regrouped and were ready to wage war on the humans once more. However the time spell went wrong, and the island of Hybras was catapulted into Limbo, where it has remained for ten thousand years.

Artemis Fowl is no stranger to trouble. In fact he's a magnet for it. Man-eating trolls, armed and dangerous (not to mention high-tech) fairies, flame-throwing goblins - he's seen the lot. He had decided to forego criminal activity of the more magical kind. However . . . Now his mother is gravely ill. He must travel back through time to steal the cure from the clutches of the devious mastermind . . . Artemis Fowl. That's right. With fairy ally Captain Holly Short by his side, Artemis is going back in time to do battle with his deadliest enemy yet. Himself.

Artemis has committed his entire fortune to a project he believes will save the planet and its inhabitants, both human and fairy. Can it be true? Has goodness taken hold of the world's greatest teenage criminal mastermind? Captain Holly Short is unconvinced, and discovers that Artemis is suffering from Atlantis Complex, a psychosis common among guilt-ridden fairies - not humans - and most likely triggered by Artemis's dabbling with fairy magic. Symptoms include obsessive-compulsive behavior, paranoia, multiple personality disorder and, in extreme cases, embarrassing professions of love to a certain feisty leprecon fairy
