Timeless kicks off the Generations trilogy (books 34-36 in the larger Drizzt saga). I enjoyed it a lot because the contrasting world views of Drizzt, Jarlaxle, and Zaknafein make for interesting ethical debates, which Salvatore loves to interweave with the fierce action scenes. You don't need to have read the previous 33 books to follow this one, but I'd recommend Homeland and The Pirate King.
