Artemis Fowl

Thirteen-year-old criminal mastermind Artemis Fowl must join forces with his nemesis, Captain Holly Short of the LEPrecon fairy police, in order to save his father--one of the few people in the world Artemis loves--who has been kidnapped by the Russian Mafiya.

Teenager Artemis Fowl solves a temporal equation that helps him and Captain Holly Short track fairy demons who are appearing from another dimension, but there is another person who has figured out the formula and abducts one of the beings.

Artemis Fowl, having reverted to his criminal lifestyle following his last run-in with the fairies, travels to Berlin intending to steal a famous painting from a German bank, not realizing his old rival, Opal Koboi, has been just waiting for a chance to destroy him.
