Though robbed by a masked spellcaster and left for dead by a demon, twelve-year-old Maimun refuses to give up the magic that rightfully belongs to him. After reuniting with dark elf Drizzt Do'Urden and Captain Deudermont's crew, Maimun sets off on a sea-faring chase that will test both the strength of his spirit and of his friendships. As perilous storms rock Sea Sprite and vicious pirates bombard its decks, a mysterious force gathers in the Moonshaes, determined to bring Deudermont's ship - and Maimun's quest - crashing to an end on its shores.
