The three words come to mind when discussing Artemis Fowl II, the son of Angeline Fowl and Artemis Fowl Senior, are "teenage criminal mastermind". After all, Artemis Fowl was only twelve-years-old when he managed to separate the Fairies from their ransom gold in exchange for one of their police officers, Holly Short. He was only thirteen when he put together a C Cube, or a conglomeration of human and fairy tech that was fifty years ahead of modern technology. He was about to find a demon, the lost Fairy kind, at age fourteen, and traveled through time in Artemis Fowl: The Time Paradox. He was also able to kidnap and kill a lemur at age ten.
