While this is somewhat of an old thread, I'd like to go on record stating that the first three books of the Legend of Drizzt are my least favorite. I absolutely disliked them. Probably because I read the other fourteen books (chronologically speaking) first. By the time I cracked open Homeland, I really knew all that I needed to know about Drizzt's past: He was a Dark Elf, they really weren't welcome on the surface and the Underdark was a crazy, messed up place.
So to me, the prequels were just a prolonged, unnecessary elaboration of things I already knew. But hey, I hope you get a real kick out of them.
