From my Heyer shelves.........
The book we are reading in The Heyer List is SIMON THE COLDHEART.
Georgette Heyer published Simon in 1925. It is set during Medieval times, and is a very good Heyer read. If you are used to just reading her Regencies you will still enjoy Simon; Heyer's humor and wit are prevalent throughout. My paper back has a forword written by Heyer's daughter.
I have a paperback copy and a hardcover with dust jacket on my shelves. The hard cover copy is in excellent shape, as near perfect as if it were brand new.
