The Artemis Fowl franchise keeps rolling along. Often dubbed "the Irish Harry Potter," written by former schoolteacher Eoin Colfer, the fourth book in the Fowl series is now out, entitled "The Opal Deception." In this latest adventure for kids and teens, Artemis, the brilliant 14-year-old mastermind, has had his mind wiped clean of all previous knowledge - including the secret world of battling fairies in which he exists. The biggest problem is that he cannot recall all of the positive lessons he has learned. Will Artemis be tempted to turn to the darkside? Pick up "The Opal Deception" and find out.
