Query: Educational and a great read too!

I am usually more into light reading, fiction type stuff but I really enjoyed this book. There was so much I did not know about 'Harem Life' and even more that I assumed, but was completely wrong about. There were some parts that got a bit dry and dull causing me to start skimming, but overall the book was a great read.
