Artemis Fowl and the Last Guardian (also Artemis Fowl: the Last Guardian) is the eighth and final novel in the Artemis Fowl series. The book was mentioned by Eoin Colfer when he stated that The Atlantis Complex was the penultimate (second to last) book of the Artemis Fowl series and would be followed soon after by the finale.Seemingly nothing in this world daunts the young criminal mastermind Artemis Fowl. In the fairy world, however, there is a small thing that has gotten under his skin on more than one occasion: Opal Koboi. In The Last Guardian, the evil pixie is wreaking havoc yet again. This time his arch rival has somehow reanimated dead fairy warriors who were buried in the grounds of Fowl Manor. Their spirits have possessed Artemis’s little brothers, making his siblings even more annoying than usual. The warriors don’t seem to realize that the battle they were fighting when they died—a battle against humans—is no longer neccesary. Artemis has until sunrise to get the spirits to vacate his brothers and go back into the earth where they belong. Can he count on a certain LEPrecon fairy to join him in what could well be his last stand?
