This is the sixth book from the Artemis Fowl series, and is as good as all the rest. By legendary Irish writer Eoin (pronounced Owen) Colfer. Eoin specializes in children's novels, and the Artemis Fowl ones are his best. Based around a human genius at the age of twelve. Artemis has met the Fairy world in his previous adventures. He is companied with his bodyguard Butler, and his Fairy friends Captain Holly Short, Mulch Diggums, and No1... Artemis finds his mother ill in bed, and realizes from Fairy knowledge, that the animal needed to cure his mother, was killed by himself- sold to the Extinctionists, to aid in the finding of his lost father. In order to save his mother, he needs the time travelling help of his friend No1, and the specialized skills of the Fairies. Artemis Fowl has to face his deadliest enemy yet. Himself. As well as a devious young elf and some caged Extinctionists. This book is possibly not the best in the series, as it is confusing some of the time, as to what character, considering there would be two Artemis' as well as an enemy Butler. It is brilliant fantasy though, and deserves praise. This book may be for children, but an adult could read it quite happily as it has all the makings of a great read. This is an inventive mix of myth and modernity, magic and crime, and well worth buying.
