Artemis is at boarding school in Ireland when he receives an urgent video e-mail from Russia. In it is a plea from a man who has been kidnapped by the Russian Mafiya -- a man Artemis had thought he would never see again: his beloved father. As Artemis rushes to his rescue, he is stopped by a familiar nemesis, Captain Holly Short of the LEPrecon fairy police. But this time, instead of battling the fairies, he is going to have to join forces with them...

After his last run-in with the fairies, Artemis Fowl's mind was wiped of memories of the world belowground and any goodness grudgingly learned is now gone with the young genius reverting to his criminal lifestyle.

After Artemis uses stolen fairy technology to create a powerful microcomputer and it is snatched by a dangerous American businessman, Artemis, Juliet, Mulch, and the fairies join forces to try to retrieve it.

When demons begin appearing on Earth unpredictably, foreshadowing a cataclysmic breakdown of their magic, Artemis and his friends face a new foe--a twelve-year-old girl whose intellect just might match Artemis's own--as they try to prevent catastrophe.

When a twelve-year-old evil genius tries to restore his family fortune by capturing a fairy and demanding a ransom in gold, the fairies fight back with magic, technology, and a particularly nasty troll.

In order to free his father from the Russian Mafiya, Artemis must join forces with the fairy police and his familiar nemesis, Captain Holly Short.
