The Fisherman by John Langan
The story follows Abe, a guy who turns to fishing to deal with the loss of his wife. He ends up meeting Dan, another widower, and the two hit it off, bonding over their grief and fishing together.
Eventually, they hear about this strange spot called Dutchman’s Creek. Locals warn them about creepy legends tied to it—especially about this supernatural figure known as The Fisherman, who’s rumored to bring back the dead, but at a heavy price.
From there, the book shifts into a story-within-a-story, diving deep into the backstory behind the legend, about 80% of the book.
As they dig deeper into the area's history, things get weird and unsettling, blending ghost stories, old-world magic, and cosmic horror for a very lovecraftin feel
