I loved this book.

While not one of Ursula's true horror novels, it is a dark fantasy, and I found the setup to be quite grim, and The Thing <spoiler>with Toothdancer</spoiler> really got to me, in a way that most of her other books don't. Once the story got going though, it was wonderful - an adventure romp through strange, mysterious and terrifying places, a motley crew with varied talents using them to solve problems in usual ways, and a satisfying ending. Recommend.
