For collections where nautical folk horror circulates well and readers enjoy slow-bloom narratives, place this behind authors like John Langan and Gemma Files. Adult audience; teens who read up may struggle with the pacing and the elliptical lore.
Content notes: blood and cutting imagery, stalking, drowning imagery, grief and funerary detail, implied coercion in relationships, alcohol use, sleep deprivation. Nothing gratuitous, but the cumulative chill is heavy.
