The book focuses on the different relationships shared by the last 13 presidents - the secrets they shared, the battles they fought and the problems that only they can understand. When you think about it, it's amazing to have a job that only a handful of other people in the world can comprehend. The book is a great historical review, but it almost reads like fiction because the events are larger than life and the situations faced by the characters are so intense. You don't have to love U.S. history to enjoy the book...but if you do, it gives you a behind-the-scenes look at the oval office from the small circle of people who really know. Pick it up - you'll be hooked pretty fast, I think.
