Perfect for you if...

  • You love hard sci-fi concepts grounded in real physics and want to see them explored through genuine human stakes.
  • You enjoy survival thrillers with genuine peril where characters can't just brute-force their way out with tech.
  • You're drawn to stories about identity and choice, especially ones that pit nature against nurture in unexpected ways.

Maybe not for you if...

  • You prefer character development to unfold slowly across multiple books; this is tightly plotted over five days.
  • You want a light read; the science is substantial and the plotting demands your full attention.
  • You're squeamish about evolved predators and the messy reality of an accelerated ecosystem.

About this book

The Twin Paradox is set in a remote stretch of Texas coast where time moves at an altered rate—ten years pass for every three minutes. This time distortion, created by government efforts to slow down time, has resulted in planes falling from the sky, evolved species hunting, and deaths within a newly formed and dangerous ecosystem. Governments pursue scientific breakthroughs and technological advantages, processes that require time. When the experiment goes wrong, the consequences unfold over five days. The novel explores themes of self-acceptance, self-confidence, and natural selection while examining the question of nature versus nurture. At its core, the story asks: Do we get to choose who we are?
