It is an account of the traumatic period of the middle ages in which royal authority was circumvented by the nobility following the inept rule of Henry VI. However, Carpenter accredits Edward IV with the effective re-establishment of the crown's power. This contrasts greatly with the views of Pollard and Horrox, who are more critical of Edward IV's achievements.
The centrepiece of the book is the reign of Edward IV and this is also the most controversial. Although it is true that Edward reasserted royal power following the Lancastrian rule of Henry VI, Carpenter largely uses this as a justification for praising him as 'the greatest medieval monarch'. This is perhaps too great a praise for a king who failed to pass on the crown to his son and whose marriage contributed greatly to the fall of the Yorkist Dynasty.
It is an in depth book which delivers an overview of the period in question. However, I do think that the effective eulogising of Edward IV goes too far. It is a very lucid text and does give an insight beyond that originally outlined by McFarlane. It is a very enjoyable book to read but I do not think it is outstanding and does not go beyond other recent books in its analysis of events.
