in my book, "Jerk" by Jonathan Friesen, the main characters name is Sam Carrier. Sam carrier suffers from Tourette's syndrome, a disease that causes him to twitch uncontrollably. He lives in a rural area and his father is deceased. As a result of his Tourette's, Sam became a runner and joined the track and field team in his high school. He spends a lot of time laone as well. On a rainy day while Sam was on a run, he saw a girl running in the wrong direction. He followed the girl and when he caught up to her he informed her that she was going to get lost. While trying to talk to her, he fell on his face and into mud. He learned that the mystery girl went to a rival high school and wants to know more about her after this encounter. Sam has a widowed mother and an abusive stepdad. He doesn't have many friends at his high school, Mitrista.
