Input: This book is an interesting look at the relationship between President Kennedy and his attorney general. When it was written this was, of course, very controversial because of their respective attitudes regarding Communism. That being said, I have to say that while interesting, there were too many references from books on JFK that could not be found in this book.
Output:
Bad review
