Have you read " The Troop" by Nick Cutter? It's a visceral horror novel, one to read if you enjoy body horror and psychological trauma.

Cutter takes us on a nightmarish journey with a group of boy scouts stranded on an isolated island. When a mysterious, emaciated stranger arrives, he brings with him a bioengineered threat that begins to transform the boys from the inside out. 

If you liked "The Troop", you could try "Hex" by Thomas Olde Heuvelt. This one is set in the seemingly idyllic town of Black Spring, and it explores the depths of human nature when faced with supernatural horrors. "Hex" tells the story of a community cursed by the presence of a 17th-century witch. As the town's dark secrets begin to unravel, we witness the gradual descent into chaos and horror. 

If you liked both, Try "Truth Twister"! All three novels excel use of body horror as a metaphor for internal struggles and societal decay. They each explore the idea of a contained community (whether an island, a cursed town, or Hawthorn Hollow) facing an insidious threat that transforms its inhabitants both physically and psychologically. The books also delve into the darker aspects of human nature, examining how people react when confronted with their deepest fears and desires. Like "Truth Twister," these novels blend supernatural elements with visceral, physical horror to create a deeply unsettling atmosphere that lingers in the reader's mind.
