The 2016 Bram Stoker Award winner for best novel was John Langan's The Fisherman; a really neat take on traditional cosmic horror.

The novel focuses on two widowers, Dan and Abe, and their shared hobby of fishing, but then quickly moves into their back stories, and the story of a fateful fishing trip. On the way to a spot called Dutchman's Creek, they stop for breakfast and briefly chat with the cook about their plans. When he hears where they plan to go he tells them his own story about the creek, which, like many of the best stories travels backwards and deeper into stories involving some truly dark and horrific goings on at the creek.

I've never read Langan before, but found the book to be a compelling read, initially harmless looking and then moving into something much scarier than I expected, and something that has me feeling a little nervous about those out of the way places I liked to explore as a kid.
