Description

A wall isn’t the only thing dividing the ruined city of Ignis.


In a post-apocalyptic world of gleaming towers and crumbling slums, the high-tech Inner Ring thrives while the Outer Ring fights to survive. Political corruption runs deep, and the government’s grip tightens daily. Rebels like The Outsiders are branded as terrorists—except for those trapped in the shadows, they’re the only hope left.


For Theopold Kraken, a genetically-engineered Recombinant with enhanced abilities, rebellion is more than survival. It’s a cause worth dying for. When Yin, a mysterious woman who may not be entirely human, crashes into his path, everything changes. She’s secretive, strange, and dangerous... and Kraken can’t walk away. As their fragile alliance deepens, he sees in her not just a failed experiment, but someone who longs for freedom—just like him. 


Yet trust is lethal. And saving her may cost him everything he’s fought to protect.


Yin doesn’t remember much, but she knows she’s being hunted. Built for a purpose she’s no longer sure of, emotions were never part of the design. Though Kraken’s loyalty and stubborn compassion stir something unexpected in her: curiosity, respect, and the terrifying whisper of humanity. As she strays from what she was made to be, Yin faces a choice: embrace the humanity she was programmed to ignore or run from it forever.


Two broken souls. One chance at freedom. In a world where trust can kill you, choosing each other might be the most dangerous act of all.


A wall isn’t the only thing dividing the ruined city of Ignis.

Advance Praise

"For fans of Veronica Roth, Isaac Asimov and Suzanne Collins, I highly recommend this book. Caenogenesis hits that sweet spot between philosophical sci-fi and dystopian thriller, and its page-turning prose and lovable characters will keep you turning pages well into the night." by Maria Ashford for Book Shelfie

"Tasha He’s Caenogenesis is an ambitious and spectacularly executed novel, in a postwar Ignis, where the titular term “caenogenesis” refers directly to an altered development of inherited patterns, and its application to Yin’s engineered genome. The author's tech is as brilliant as the world-building. This is an intelligently written introduction to a new series, and I'm excited to see what comes next. Very highly recommended." by Jamie Michele for Readers’ Favorite
