There are periods of English history I am ashamed to say I have had to learn through fact based fiction. So thank you to the likes of Bernard Cornwell and now James Wilde.
I had never heard of Hereward, but he did exist and fought against the Normans after their invasion of 1066. In many ways he reminded me of Robin Hood, but his existence is fact compared to the legend of Robin Hood, in addition to preceding him by 150 years.
We see Hereward as a young man forced to leave the emerging English court because of his unruly behaviour and then allegations of murder. His character is wild, intense and unpredictable (reminded me of the sort of character then late, great David Gemmell produced) with a dark side kept barely in check. Hooking up with a young priest, also on the run, Hereward is struggling to discover a goal and self value, but once the Normans invade, he sees his duty to defend England against the Norman tyranny.
The Normans occupied England (not Scotland or Wales) and pretty much dominated it all, Hereward was based in the Isle of Ely and the Fens, an inhospitable area that the Normans struggled to gain control over. The original outlaw he ran a running campaign against the Normans. This book deals with his early years from exile to the start of his campaign against the Normans and it is interesting, page turning stuff.
