The Haar by David Sodergren is a folk horror novel about an elderly woman, Muriel McAuley, in a Scottish fishing village threatened by developers, who finds a mysterious, sentient ooze creature in a fog bank (the "haar") that helps her fight back with extreme, gory violence, blending themes of greed, love, loss, and body horror. It's described as a "gore-soaked folk horror fairy tale" with a mix of John Carpenter-style body horror and a heartfelt, emotional core, often compared to The Thing.
