A glorious novel set in seventeenth-century London, and in the fairy world.

Someone has been supplying Class A illegal human power sources to the goblins. Captain Holly Short of the LEPrecon Unit is sure that her arch-enemy, 13-year-old Artemis Fowl, is responsible. But is he? Artemis has his problems to deal with: his father is being held to ransom and only a miracle will save him. Maybe this time Artemis needs help.

Evil pixie, Opal Koboi, is back and she's more dangerous than ever. This time she doesn't just want power over the fairy People - this time she wants the humans too. Captain Holly Short is the only fairy with a hope of stopping her, but as Holly knows, it takes one genius criminal mastermind to fight another.

13-year-old criminal mastermind Artemis Fowl has constructed a supercomputer from stolen fairy technology. In the wrong hands it could be fatal for humans and fairies alike. But Artemis has a plan. He's not going to use the computer; he's just going to show it to an American businessman with Mafia connections. What could possibly go wrong...?
