I was trying to get rid of some paperbacks and somehow started rereading this. I'm glad I did.
I think this author had/has more successful books, in terms of popularity, and that's likely due to what she gets right:
The story takes place in 1345/1346 and mercifully the characters act, behave, and speak accordingly. There is no presentism.
Romance readers need have no fear as this is a love story albeit among people who live in their times and their reality. It was glorious.
Needless to say this paperback stays.
ps. I don't know that this series needs to be read as a series or in any particular order.
