Perfect for you if...

  • You love high-concept thrillers that blend cutting-edge science with deeply personal stakes, like Dark Matter or Recursion.
  • You're drawn to protagonists who gain extraordinary abilities but face impossible moral choices about what they're becoming.
  • You want page-turning speculative fiction that asks serious questions about human evolution and free will without slowing down the plot.

Maybe not for you if...

  • You prefer character-driven literary fiction over plot-driven narratives with big ideas.
  • You find transhumanism and genetic engineering storylines more tedious than thrilling.
  • You're looking for a standalone that won't make you think about its premise long after you finish.

About this book

Logan Ramsay begins to notice subtle changes in his mental abilities—sharper focus, better concentration, improved multitasking, faster reading, and enhanced memory. He requires less sleep than before. As these changes intensify, Logan realizes something significant is happening to his brain and body. He starts perceiving the world and the people around him, including those closest to him, in entirely new ways. The cause becomes clear: his genome has been hacked. Logan discovers he was deliberately targeted for this upgrade. The reason traces back decades to a dark chapter in his past and a horrific family legacy. What's happening to him is only the beginning of a larger plan designed to inflict the same changes on all of humanity—with devastating consequences. Because of his new abilities, Logan is the only person capable of stopping what has been set in motion. To have any chance of success, he must transform himself further, potentially into something beyond human. Throughout his struggle, he grapples with a troubling question: might humanity's only path forward actually depend on engineering our own evolution?
