Erosion is a story by Lon S. Cohen, who has made it available as a free digital audiobook.
The story is about a Native American, driven to madness by his experience growing up in the small upstate New York town of Canyon Park being discriminated, molested and ostracized. In his mind, various characters of his tribe's mythology and American popular culture vie for his soul. He terrorizes the residents of Canyon Park, murdering those he judges guilty, to punish them for their crimes against him and his ancestors. Strangely, since the killing spree began, there has been a deluge of constant rain adding to the dismal mood and hampering efforts to stop him while the resident also battle nature's fury. Under these conditions, various characters gather from places as close as the local library, to as far away as New York City, to absolve their sins and stop their beloved town from being eroded away.
