A Stretch of Highway Two Lanes Wide is one of the better nominees for the Nebula this year. She made it available for free specifically to attract Hugo nominations, which turned out to be a waste of time. But it's still a fine story.
Our protagonist is a farmer, son of farmers, and basically content with the life. He is a young man, farming alongside his parents' place. Then he has an accident, losing his right arm. His parents are very much into technology--they "farm from an office"--and have him outfitted with a prototype prosthetic arm.
The arm believes itself to be a road. A very specific road. This plays out through the story, which is very warm and fine to read. It has a completely real feel, and madnesses have been stranger so it's not that hard to believe. Read this for an excellent example of storytelling. It's got a fine enough edge to it that I'm giving it 4 stars.
