Commonwealth

I enjoyed Commonwealth by Ann Patchett which is the story of two families.  They are broken up in 1964 when the father of one family begins a relationship with the mother of the other family.  During holidays the children of the families become "blended" when they stay with their step-mother or step-father.  A tragic event occurs some years later, which haunts them all their lives.  The story of their lives is told by each of the children.  One of the girls becomes the lover of a famous author who turns the stories of her family in to a book.  I found it a little confusing at first trying to remember the names of the children and who their parents were.  They all have interesting lives and I then wanted to know how they turned out. 4/5
