The Arctic Incident (Artemis Fowl, Book 2)

Artemis Fowl is at boarding school in Iceland when he receives an urgent video email from Russia. It's a plea from his father, who has been kidnapped by the Russian mafia. As Artemis rushes to his rescue, he is stopped by Captain Holly Short. This time, instead of battling the fairies, he's going to have to join forces with them if he wants to save one of the few people he loves.
