The Northern Caves is an extended work of surreal horror fiction. It centres on a group of fans of a fictional author and his body of work; specifically, his last book, The Northern Caves, which seems to include a secret message to his followers.
The main body is written as a 90s forum thread, while towards the end it’s a regular format as the characters meet up in person.
It was disturbing and very very well-written - I forgot that the author and his corpus were completely fictional!
