What Is Recursion About?
The story begins with a disturbing phenomenon spreading across the world:
False Memory Syndrome (FMS)
People suddenly begin remembering entire lives they never lived.
Some recall different childhoods.
Others remember alternate relationships.
Many lose their grip on reality entirely.
This leads to confusion, madness, and in some cases, suicide.
Two Main Characters, Two Timelines
Barry Sutton (NYPD Detective)
Barry investigates the rising cases of FMS after witnessing a tragic suicide connected to the phenomenon. His investigation leads him into a hidden system that can manipulate memory itself.
Helena Smith (Neuroscientist)
Helena is working on technology designed to preserve human memories. But her research becomes the key to something far more dangerous than she ever imagined.
The Core Discovery
At the center of the story is a technology that allows people to:
- Re-experience memories
- Travel through reconstructed timelines
- Alter past events
But every change creates devastating consequences.
Because memory doesn’t just record reality…
It creates it.
The Collapse of Reality
As Barry and Helena get closer to the truth, they realize:
- Changing memories rewrites the present
- Entire timelines begin to collapse
- People retain memories of multiple realities
- The world becomes unstable and unpredictable
What begins as a scientific breakthrough turns into a global existential crisis.
