My Father's Wives by Mike Greenberg Post
Jonathan Sweetwater has been blessed with money, a fulfilling career, great kids, and Claire, his smart, gorgeous, sophisticated wife. But there is one thing Jonathan never had: a relationship with his father.
This is a story of a son who is trying to find out just what his father was like and how it would effect his life. Married five times he sets out to contact all the wives, to see what they thought of his father and why he married them. In the end I think he has to realize he has to be his own person and be grateful for the life he has now. It is an interesting read.
