Stand alone books are nice because they have everything all in one tidy little package. Neverwhere was awesome because you get action, adventure, character development, the exploration of a strange world, PLUS resolution of all the problems and mysteries at the end. No lines no waiting. That's very satisfying. Multi-volume stories are satisfying too, just in a different way.
Patrick RothfussIn my opinion there are two basic questions that any writer tries to answer. "What is?" is the question non-fiction asks. "What if?" is the question fiction asks. That's the question I'm more interested in.
