Publisher's overview
""Meet Maimun—an orphan who couldn't imagine how unfortunate it would be to discover a stone that makes him forever lucky. Fleeing a powerful demon named Asbeel, Maimun stows away aboard the ship Sea Sprite, where he encounters a cast of characters well-known to Salvatore fans: Captain Deudermont, Drizzt Do'Urden, Wulfgar, Catti-brie, and the dwarf Bruenor. Drizzt becomes a mentor to Maimun and aboard Deudermont's ship, they sail the treacherous seas of the Forgotten Realms. Hunted by a demon, haunted by a mysterious spellcaster, and chased by a pirate, Maimun, with Drizzt's help, must unravel the secrets of the Stone of Tymora before his luck runs out!""
