I requested this book here on the recommendation of a friend, but did not read it. Skimmed a bit and it was far too raw for my taste.
My friend read it twice, once just for story line, then a 2nd time to understand the psychological aspects of it.
Back cover of book says, "This is not fantasy. It is a diary of a woman who gave herself unconditionally for 9-1/2 weeks to a man she hardly knew. It is perhaps the most powerful erotic book ever written by a woman.
