I have just begun work on a new series about the rise of the Normans. It begins in the ninth century and features Hrolf who appeared in Viking Vengeance. he was too good a character to discard and I have been researching him ever since I wrote the book. it may take longer than my normal books as it is a new venture; please be patient. As I am travelling up to Northumberland for a week to research my next Anarchy book I do not expect to be able to get Hrolf out until May.
