Discovering a way to build a super-computer using stolen fairy technology, young criminal mastermind Artemis sets out to blackmail a Chicago businessman but runs into a trap that leaves Butler mortally injured.

Two original short stories, plus puzzles, interviews with characters, and other writings that unlock secrets of the Artemis Fowl books, which feature a twelve-year-old evil genius and his dealings with fairies and other magical beings.

When demons begin appearing on Earth unpredictably, foreshadowing a cataclysmic breakdown of their magic, Artemis and his friends face a new foe--a twelve-year-old girl whose intellect just might match Artemis's own--as they try to prevent catastrophe.

Opal Koboi, power-crazed pixie, is plotting to exterminate mankind and become fairy queen. If she succeeds, the spirits of long-dead fairy warriors will rise from the earth, inhabit the nearest available bodies and wreak mass destruction. But what happens if those nearest bodies include crows, or deer, or badgers -- or two curious little boys by the names of Myles and Beckett Fowl? Yes, it's true. Criminal mastermind Artemis Fowl's four-year-old brothers...

Taking the Fowl jet without permission before it mysteriously explodes over Florida, the Fowl twins are placed under house arrest until Myles's questions about what really happened lead to an astonishing abduction.
