“[Artemis Fowl] will grab your interest, no matter what your age.”
—The New York Post

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 in guilt-ridden fairies. Symptoms include obsessive-compulsive behavior, paranoia, multiple personality disorder and, in extreme cases, embarrassing professions of love to a certain feisty LEPrecon fairy.

Unfortunately, Atlantis Complex has struck at the worst possible time. A deadly foe from Holly’s past is intent on destroying the actual city of Atlantis. Can Artemis escape the confines of his mind—and the grips of a giant squid—in time to save the underwater metropolis and its fairy inhabitants?

Artemis Fowl has lost his mind... Just when the world needs him most.
