The Returning by Christine Hinwood
This book begins with several detailed hand-drawn maps for upland, just like those we expect to see in epic stories. The figure on the cover is one-armed Cam. When Cam came back home after the war, his sister was a cute silly country girl busy catching snails with the family, but at the end of the book, she grew to be a dress maid for the upper land Lady.
Amazing fates for different persons intertwined in the story.
