Artemis Fowl's archenemy Opal Koboi has masterminded a way to simultaneously secure her release from prison and bring the human and fairy worlds to their knees.

Ground zero is the Fowl Estate, where Opal has reanimated fairy warriors whose spirits have possessed any vessel they can find--corpses, Artemis's little brothers, assorted wildlife--and they are bound to obey Opal's every command. Defeating the motley troops and their diabolical leader will require all of Artemis's cleverness--as well as Butler's bravery, Holly's skill, and Foaly's gadgetry. But if their best efforts aren't enough, Armageddon will surely follow.
