Thomas B. Costain 
The Conquering Family [EPUB ebook] 

Thomas B. Costain's four-volume history of the Plantagenets begins with THE CONQUERING FAMILY and the conquest of England by William the Conqueror in 1066, closing with the reign of John in 1216.
The troubled period after the Norman Conquest, when the foundations of government were hammered out between monarch and people, comes to life through Costain's storytelling skill and historical imagination.
