I read a book a few years ago that was set on a farm in Canada. The narrator was looking back on her teenage years remembering a guy that came to work on the farm. She was jealous and thought that her mother was involved with the guy but he was actually having an affair with her brother, who had a name like Bryan or Byron. There was a fire involved somehow. I usually have a good memory for names and trying to remember this is bugging me so much.
