Artemis Fowl and the Opal Deception, known in America as Artemis Fowl: The Opal Deception, is a teen fantasy novel published in 2005, the 4th book in the Artemis Fowl series by the Irish author Eoin Colfer. Preceded by Artemis Fowl: The Eternity Code and followed by Artemis Fowl: The Lost Colony, it is centred on the brilliant pixie Opal Koboi's second try at rebellion (after her first attempt was a failure) and Artemis Fowl II and his fairy comrades' efforts to stop her. Critical reception was mixed, with some reviews praising the book and others deeming its writing poor and confusing. Plot The book begins with the pixie Opal Koboi faking a coma inside a hospital to avoid incarceration by the Lower Elements Police (LEP) after her failed rebellion and attempt of world domination (which took place in Artemis Fowl and the Arctic Incident). Opal Koboi, who had been under 24-hour surveillance, had DNA tests done every 4 hours, a seeker-sleeper planted in her arm (a device that can make the criminal faint, while also giving their position away) and had her in a net trapped with monitoring pads by the LEP to ensure that Opal was actually in the asylum cell, with help from the Brill Brothers Opal manages to replace herself with a clone, which is identical to herself (the only difference being that the clone is brain dead which is also the current state the sensors detect Opal's coma-like mind to be in). Opal lures Commander Julius Root and Captain Holly Short of the LEP into a lava chute alone by putting General Scalene under the mesmer there. Koboi then kills Commander Root by using a 30-centimeter metal box packed with explosive gel and covered in stealth ore (framing Captain Holly Short as the murderer, she told Holly that if she shot a certain part of the exploding box, it would turn off (it only went faster), since stealth ore couldn't be picked up by any electronics the LEP cameras only saw Holly shooting the commander, clear as day), and launches a bio-bomb at Artemis Fowl, which fails to kill him and his bodyguard Domovoi Butler because Butler grabbed Artemis and jumps from the three-story hotel, using a mattress to cushion the fall. Artemis Fowl was mindwiped in the third book of the series, Artemis Fowl and the Eternity Code and has no memory of meeting
