I absolutely loved this book. I wasn't sure what to expect at first. I actually thought it was going to be a farce, but it is actually historical fiction. The affair really happened as did many of the "facts" of the book. It is the in between stuff that has been made up.
Mamah (May - ma) is married when Frank meets her. She and her husband are actually his client. But I guess, alas, love is love and they begin an affair which causes Mamah to leave her family, her children, and even her country for a while. The book gives insight to Frank, to women of the era, and to the complications of an affair.
I won't give anything else away, but the ending is shocking.
I hope you will pick it up and enjoy it as much as I did.
