Artemis Fowl has built the C Cube, a supercomputer constructed from stolen fairy technology that will render all human technology obsolete. Planning to blackmail ruthless businessman Jon Spiro, Artemis arranges a meeting—but the deal goes disastrously wrong. Spiro steals the Cube, and his bodyguard shoots Butler, Artemis's loyal protector. To save Butler's life, Artemis calls on his old adversary, Captain Holly Short. Now, together with Holly and the dwarf convict Mulch Diggums, Artemis must break into Spiro's heavily guarded Chicago headquarters to recover the C Cube—before fairy technology falls into human hands and exposes the hidden fairy world forever.
