To my mind the best part is going in blind, cause the ideas are what makes it. To me the first half/three quarters are excellent, then it was just OK.

There's an organization that deals with weird, anomalous stuff in the world; their antimemetics division specifically studies things that make you forget information. Part of their mandate is figuring out how to protect against world-ending phenomena that can't be remembered... like the one creeping up on them right now.

If you like SCP or the game Control, this is liable to be your jam.

The book began life as a series of stories set in the world of the SCP Foundation. If you're a fan of that kind of cosmic mystery/horror it's a must-read.

Well - it's inspired by the SCP Foundation wiki. The guy who wrote it was a prolific poster to that. Some of what's in the book was actually posted by him in serialized format there; in fact, there's even a video series covering some of the stories:

If the videos seem like your cup of tea, you should give the book a read.
