I really really like Diana Wynne Jones and this was the first one of hers I read so I'm sure some of the love for this particular book is from the excitement I felt at the time, when I realised a) this is really good! and b) there are a lot more!! But its still a really good book with a strong flavor of that elusive quality of dreams and tales, where it all makes emotional sense though clearly not working within the logic of the everyday world.
