This is a long shot, but I'm looking for a medieval novel published in the 90s, with a bright medeival type jacket design, illuminated letters and a very pretty design of medieval figures on it .I seem to recall the background being bright blue.
I seem to recall it was about a man who had two daughters, bizarrely , I can recall their names were Johanna, and Janot. One of them was going to be sent to a convent because she kept turning down suitors. The younger sister was pretty and ended up marrying a knight, I seem to recall?
