Grade 5-7 -Identity fraud is at the heart of this fourth book in the series. To all appearances, Opal Koboi, pixie and archenemy of the fairies, is under close surveillance as she lies in a coma. Artemis Fowl, the brilliant 14-year-old criminal mastermind, has had his mind wiped clean of all knowledge of fairies, and, therefore, of all prior goodness he has learned. When the real Opal escapes and leaves behind a DNA-perfect clone of herself, her revenge against all those who opposed her commences with deadly fury. Among the barrage of high-tech gadgets and continuous action sequences and plot twists are moments that give even Artemis Fowl pause as he contemplates friendship, responsibility, and death. The prose is clunky and the characters speak in clichΓ©s, but those who enjoyed the earlier books won't care. The humor (heavily dosed with flatulence jokes) and creativity carry the narrative through the tight spots and impossible situations.-Farida S. Dowler, Mercer Island Library, WA

From Booklist
Gr. 6-9. The fourth book in the Artemis Fowl saga follows The Eternity Code (2003), in which Artemis' mind was wiped clean of any memories of the belowground world of elves, pixies, and dwarves. In this book, Artemis has reverted to his old life of crime. His archenemy, Opal Koboi, has been in a self-induced coma for a year, plotting revenge on all who thwarted her earlier evil doings. After cloning herself, she escapes and sets her plans in motion, going first to find LEPrecon Captain Holly Short and Commander Root, then taking on Artemis as she schemes to destroy the fairy world. As in all the books, this one has plenty of action as well as great humor and clever plot manipulations. Characters are once again fully realized, and fans will eagerly enter into the spirit of the action. Sally Estes
