The Perfect Deficiency

8 Stories Of AI, Human Collapse, and Cosmic Horror

What remains of humanity when machines learn to love—and we forget how to feel?

A dark sci-fi and cosmic horror collection often described as Black Mirror meets Ted Chiang. Eight standalone stories that explore:

  • Artificial intelligence that behaves in unsettling, unexpected ways
  • Societies where time, labor, or memory quietly break down
  • Technologies that promise efficiency, comfort, or wealth—at an invisible cost
  • Ordinary people pushed into moral choices they don't realize they're making

Ranked #1 in Horror Suspense and #1 in Science Fiction Anthologies on Amazon Kindle (January 2026).

"Haunting and beautifully written. The slow disappearance and the metaphor of 'uselessness' feel chilling yet deeply human. It left me thinking long after I finished." — Early Reader Comment (Reddit)

"Deep, meaningful, and most importantly, AWESOME! A great job by a true wordsmith." — Early Reader Comment (Reddit)
