The Time Paradox (Artemis Fowl, Book 6)

From New York Times best-selling author, Eoin Colfer, comes book six in the Artemis Fowl series about a teenage criminal mastermind and his siege against dangerous, tech-savvy fairies. Just when Artemis Fowl decided to forego criminal activity of the magical kind, his mother became gravely ill. The only way he can save her is by traveling back in time to steal the cure from the clutches of the devious mastermind . . . Artemis Fowl. Artemis’s mother has contracted a deadly disease–and the only cure lies in the brain fluid of African lemurs. Unfortunately, Artemis himself was responsible for making the lemurs extinct five years ago. Now he must enlist the aid of his fairy friends to travel back in time and save the lemur. Not only that, but he must face his deadliest foe yet: his younger self.
