Artemis is at boarding school in Ireland when he suddenly receives an urgent video e-mail from Russia. In it is a plea from his father, who has been kidnapped by the Russian Mafiya. As Artemis rushes to his rescue, he is stopped by 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 if he wants to save one of the few people in the world he loves.
