Query: Fascinating subject - hard to put down

After reading several books lately which took place in Japan, I was interested to learn more about geishas. Since I had purchased this book several years ago, it was a perfect time to read it. The book was very interesting, very sad, very informative. It appeared the ending was going to be tragic. Instead it had a delightful twist. It didn't make for a fairy tale happy ending, but it made the ending something I could accept and believe. I highly recommend it, especially for women.
