Thanks. I saw the list and I don't think it's accurate. Norah Hess's books are set in still settling western world and her characters are blue-collar workers, generally trappers and ranchers. I think any algorithm generated list would have difficulty matching her up with other authors. I posted hoping someone who's read her works will be able to chime in with rec.
I think Maggie Osbourne's books are closer to her settings and nature but they lack the ugly and grittiness of Hess's work.
