Mr Cornwell, I am just about to enter my second year at the University of St Andrews, studying Mediaeval History, and the period we are about to cover is Britain from the ninth to the thirteenth centuries. Having just devoured Sword Song with the utmost pleasure, I was wondering whether you could offer me the names and book titles of a few historians who cover that period for some background reading and for the essays I will have to endure? Many thanks and my compliments on another fantastic book. Regards, Al.
