So I just finished this book off this morning.
Then I'm trolling the freebies today and found this.
The Linda Hilton book mostly takes place during Napoleon's Russian campaign, published 1980s. A bit on the cray-cray side at times and it does have some of those 1980s tropes that don't work well for the PC readers, but I enjoyed it. The Afton Bonds book takes place in New Mexico, 1920s I think. Originally published 2001 as When the Heart is Right.
Edit, the Afton Bonds book is free today on Kindle.
