Diana Wynne Jones, as always she has written an absolutely wonderful book. I was drawn in from the very beginning and was not let off the hook until the very end. The only reason I gave this delightful book only three stars was the ending. Or the lack thereof, as the case may be. Honestly, I wanted to read more. I wanted to see how the friendship between Heather and Robert progressed. I also wanted to see whether or not the relationship between Mr. McManus and Heather changed. And, what happens with Robert, Heather's parents, and the Castlemaine situation??? Overall, this book felt more like a first chapter instead of an actual book. It definitely left me wanting to read more without delivering any satisfaction, and that is why it only gets three stars. If Diana Wynne Jones had given a little more closure in the ending, the book would have easily gotten five stars from me.
