This is the second in the series written by James Wilde about Hereward who led an English revolt against the Norman conquest from the Fen country in East Anglia.
This isn't a revolt, or for that matter a region of England, I know a lot about. So I can't vouch for how far the author deviates from the history. However, it's a good story well told with all the essential elements of a good historical novel.
Our hero battles with Normans from a relatively safe base in the Fens, somewhat more treacherous than they are today. There is treachery, romance and even a temporary alliance with a Danish army. We also get to see the other side of the hill through the eyes of an English collaborator in the Norman camp.
I enjoyed the first in this series, but for some reason found the second a little harder going. Not sure why as it has good reviews and it may be that I read it sporadically without really devouring the characters. It would make a good skirmish game using Saga rules.
