Passage to Dawn. The Legend of Drizzt

Danger awaits Drizzt Do'Urden and Catti-brie on the high seas in this fourth and final installment in the Legacy of the Drow seriesIt has been six years since the fateful Battle of Mithral Hall; six long years during which Drizzt Do'Urden and Catti-brie have been away from the only place they ever truly felt at home. The pain of a lost companion still weighs heavily on their strong shoulders, but chasing pirates aboard Captain Deudermont's Sea Sprite has been enough to draw their attention away from their grief.
But when a mysterious castaway on an uncharted island appears bearing a strange message, Drizzt and Catti-brie are sent back to the very source of their pain-and into the clutches of a demon with vengeance on his mind. Passage to Dawn is the fourth book in the Legacy of the Drow series and the tenth book in the Legend of Drizzt series.
