This is without doubt the definitive biography of King John! For too long dismissed as weak and cruel, this book shows him in a new and more favourable light. His skills in administering his realm, and his sporadic military genius all come together together to paint a picture of active and well informed King. The book is written well, and captures the King as if the author knew him himself. The series of the Yale English Monarchs books are clearly setting the standard for books on the Kings of England, and I hope that there are books in preparation for the remaining 'gaps' in the series. Very, Very Good!!
