I enjoyed this, but it's very much the opening book in a series and it's a personal bugbear of mine when a book just cuts off in the middle of a story. I like the ideas and most of the structure, though the opening section before the tales begin is a bit bewildering for just how much it dumps on the reader without context. But the scope and ambition of it is huge, and there's a lot to get stuck into and get you thinking - already have the next book reserved at the library!
