More like 3.5. I don't normally read books like this but this one interested me. The stories shared are very selective and Mimi doesn't go into great detail about her relationship with JFK only specific exchanges with a common theme are detailed. She did a good job explaining what kind of person she was before the affair and how she ended up getting into it and the after effects of it through out her life. She repeats herself quite a bit through out the book which can be annoying and towards the end of her relationship with JFK I question how much of it is true. The gifts, things he said about her to her, and most of all whether or not her descriptions of some of the most iconic & memorable moments of JFK's presidency took place like she described them (Missile Crisis & trip to Dallas). This is definitely worth reading if you are interested in JFK and that time period in America or even just in general because it is an interesting story.
