Fiction by Liz Curtis Higgs.
I had some trouble getting into this book. I'm not sure why, but it wasn't until about halfway through that I got really interested in the story. That's a long wait for me, but the book was worth it in the end.
This story is set in Scotland during the Jacobite Rebellion in 1745. I knew that historically "Bonnie Prince Charlie" was doomed, so my characters were not on the winning side. (When it's called a "Rebellion" that means it failed; if the rebellion had succeeded it would have been a "Revolution.") Still, the story held a surprise at the end.
