This science fiction novel poses a terrifying question: what if humanity's greatest threats were things that, by their very nature, could not be remembered or perceived? An antimeme is the opposite of a meme—an idea that resists being known, that erases itself from memory the moment attention shifts away. The story follows Marion Wheeler, a researcher at the SCP Foundation, a secret organization dedicated to containing anomalous phenomena, who discovers that an entire division of the Foundation has been fighting a war against antimemetic entities and losing, because every time someone learns about the threat, that knowledge is consumed. The narrative structure mirrors its subject: chapters jump forward in time, characters forget crucial information between scenes, and the reader must piece together what is happening alongside protagonists who keep losing the thread. The central antagonist is an entity of staggering power that feeds on information and identity, growing stronger as it devours the knowledge of its own existence from the minds of those who would fight it. The novel originated as a series of interconnected stories on the SCP Foundation collaborative fiction wiki, and its author, who writes under the name qntm, expanded and refined the material into a cohesive narrative. The result is a work that uses the horror of forgetting to explore questions about identity, institutional memory, and what it means to fight an enemy that attacks the very capacity to recognize it as a threat. The prose is precise and technically minded, building dread through logical extrapolation rather than atmospheric description.
