Look, I haven't read the book you are talking about so far then my suggestion can be easily silly.
Some years ago I read "The bridges of Madison County" (1992) by Robert James Waller and I liked it. It's the story of two people who meet and fall in love. It sounds easy but it is not, as she is married but not happy and he is a single free lance photographer.
Mind you, it's not a story of a love affair!
It deals with life, love, happiness...
It's the book the movie by Eastewood is based on.
Hoping I helped you, bye
I've watched the movie and read the book.
