Abc About a child criminal mastermind who discovers an entire race of fairies living underground that alongside using magic have high tech weaponry and systems. Artemis then kidnaps a fairy police officer "Holly Short" and holds her as a hostage demanding tonnes of gold from the Fairy council in return to release her. The series then progresses with the Fairies and Artemis Fowl cooperating together in deals that benefit them both. I would say the entire series is a must read. Don't miss it.
