I thought that Mr. Keen's book was an excellent read for the student of Medieval history. His accounts and insights of medieval religious and political thought were throughly explained. The author spends a great deal of time on the complex relationships of the Papacy, England, France, Germany, and Italy with each other. The one negative about the book is that the author spends practically no time on medieval Spain. The bibliography was good, though it should be updated. Overall a good short work for someone to get a good basic understanding of Medieval history.
