The Opal Deception — Full Chapter Overview

The Opal Deception Summary & Overview

Artemis Fowl once outsmarted the hidden fairy civilization beneath his feet. Now a mind wipe has erased every magical encounter, leaving him to pursue an impossible stolen painting with no memory of Captain Holly Short, Commander Root, or the enemies he made underground.

One enemy remembers everything. Pixie genius Opal Koboi has spent eleven months pretending to be comatose while preparing an elaborate escape. With a clone ready to take her place and loyal accomplices carrying out her orders, Opal begins a revenge campaign aimed at everyone who helped defeat her. Her plan is not merely personal. If she succeeds, the fairy world will be exposed to humanity, and the resulting conflict could destroy both civilizations.

As Artemis walks unknowingly into danger, Holly faces a trap designed to ruin her career and turn her own people against her. To survive, old allies must reconnect, buried memories must return, and a brilliant young criminal must decide whether friendship matters more than profit. Fast, funny, and relentlessly inventive, this fourth Artemis Fowl adventure pits genius against genius with two worlds hanging in the balance.
