With little material to work with Richard Fletcher has produced a very readable and highly entertaining book. Much of the material is background information and inevitably there are gaps in the history of the feud. In fact the specific feud mentioned may only take up about 25% of the book, but this is unimportant. There's lots of information here about how the kingdoms ot the English were unified, early monasticism and its later revival and plenty of information about St Cuthbert and the Lindisfarn monastery. The book thus covers a swathe of history from the north east. Of course Viking attacks feature heavily with the invasion of Cnut in 1016 being important. This book gives a good insight into the impact of having foreigners on the English throne for the first time (in 1016 and again in 1066, though there has been no English monarch on the throne since), especially on taxation. The bloodfeud itself takes a back seat for much of the book but what comes across well is the total disaster for the English of the invasions and capitulations of 1016 and 1066, leaving the native English out in the cold and treated as nothing more than second class citizens. Something the foreign nobility continued to do for centuries (and still do to a certain extent).
