This is great for book club discussion! Highly recommend for book clubs! 
 As far as my enjoyment goes, I loved the reveals and the twists and the ending, but I can't give this more than 3 stars because I didn't enjoy reading about the death of Rachel's daughter and Rachel's grief. Most women from the book club loved it or really liked it. We had a good discussion. 
 BTW, I didn't buy that Cecilia and her husband can go six months without doing it and still be fine. Cecilia just notices one day that they've been so busy it's been months, yeah right. My husband and I can barely tolerate each other for 6 days if we aren't doing it.
