Yeah, Sarum... I remember some of that one. The bossy woman who got her comeuppance by being sacrificed at Stonehenge, the people who had no clue about the Black Death and did everything exactly wrong, and the ubiquitous "fat girl" character he puts in all his books (bad enough he includes pointless body-shaming, but why is it always a teenage girl?).
It held my interest and I might re-read it some day. But when it comes to re-reading my historical novels, my go-to authors are Philippa Gregory, Lindsay Davis, and Pauline Gedge (Plantagenets/Tudors, 1st-century Roman murder mysteries, and ancient Egypt respectively).
The last historical novel I read was The Traitor's Wife by Susan Higginbotham, about the wife of Hugh le Despenser (the younger). I recently saw a YT video about the Plantagenet kings, and these characters were mentioned. Now I'm wondering if the historical Piers Gaveston had such a huge, ugly nose, or if that was just unfortunate casting for the documentary.
