Runner by Parker Williams

Matt Bowers’s life ended at sixteen, when a vicious betrayal by someone who he should have been able to trust left him a shell of himself, fighting OCD and PTSD, living in constant fear and always running. When he buys a remote tract of land, he thinks he’s found the perfect place to hide from the world and attempt to establish some peace. For ten years he believes he’s found a measure of comfort, until the day a stranger begins to run on Matt’s road.

He returns every day, an unwelcome intrusion into Matt’s carefully structured life. Matt appeals to the local sheriff, who cannot help him since the jogger is doing nothing wrong. Gradually, after tentatively breaking the ice, Matt begins to accept the man’s presence—

But when the runner doesn’t show up one day, it throws Matt’s world into chaos and he must make the hardest decision of his life.
