This book is extremely fun to read. You can get a free sample by reading the SCP-055 listing written by the same author. The core concept of the book is that there exist information with self-destructive properties. Information that, when learned, just slips out of your head.
The SCP Foundation exists to counter all sorts of world-threatening anomalies, including Antimemetic ones. The book is told as a series of vignettes, with characters recurring between them as we learn and unlearn things about antimemetic threats.
