Artemis Fowl: The Last Guardian by Eoin Colfer
In this last book of the Artemis Fowl series, Artemis Fowl’s nemesis, Opal Koboi, escapes from fairy prison with the help of her clone, and begins orchestrating the destruction of humanity. She hopes to resurrect fairy Berserkers buried on the Fowl property. Of course, Artemis and his fairy, dwarf, centaur, and bodyguard friends have to stop her. As always in this series, the book is jam-packed with improbable action scenes and witty banter. Artemis’s twin brothers are major characters this time, adding both to the humor and the stakes for their brother. Artemis himself completes the growth process that began in the first novel, becoming a hero capable of real sacrifice and impressive planning. It’s a good ending to a good series.
