The Opal Deception by Eoin Colfer

THE OPAL DECEPTION is the fourth book in the Artemis Fowl series. It starts with Artemis trying to steal a prized painting and being unsuccessful. He has been brainwashed, so he remembers nothing of the fairies. He meets Holly after an attempt on his live Opal Koboi. Opal has already killed Jullies. Holly is on the run because the Leps think she killed Jullies. Butler is left behind, and he runs into Mulch Diggums who gives him a disk that not only refreshes his memory but he immediately knows what danger they are in. They rescue Holly and Artemis from Opal and figure out the plan to give up fairies to the human race. They immediately set out to stop it and do they get Holly's good name back and get Opal. This is a really good book, and I am sure you will enjoy it. -Josh M.
