It's basically the same as the movie with a slightly different ending. I liked the book Nora better than the movie Nora but that's Hollywood for you.
Max is a tidy twnty-seven, an up and coming advertising man and devastated widower. celibate since his wife's tragic death, striving for order and reason in his uptight world. Max suddenly and shockingly finds himself careening into a torrid affair with a woman from the other side of the tracks. ....a lusty, hard-drinking passioate forty-one year old white palace waitress named Nora. This is the story of how their back breaking one night stand turns, quite remarkably into an amazing kind of love.
