Having only ever read the children's story versions of Robin Hood this came as an eye opener. This characterization as Robyn Hood was fairly well written and the story was split up nicely into manageable chunks written from various character's standpoints. The timing of the battle at Sluy and the numbers involved seemed over-the-top it was a sea battle but Robyn seems to fight it on land. The Great Pestilence was well described if a little gruesome.
But ultimately you are left wondering why the sift in time? Was it solely to underline the author's knowledge of the end of the Plantagenet period and allow him to use the Black Death to wind everything up?
