Seventeen-year-old Luke has been having more and more accidents lately: ramming his car into the side of a truck while making a left turn, cutting off his dog's tail when he was out chopping wood, almost getting hit by a barge in the middle of the night while in a boat that was out of gas. And then there are the impulsive things he's been doing, like mountain climbing with no safety gear. Luke can't understand why all this is happening, or how to stop it. Is the answer to be found in the here and now, or deep in the buried thoughts of another accident, one from long ago?
