The Final Marker

By Carrie Ray

The ultimate debt is paid in blood.

The mastermind behind the Genetic Debt program-a bio-tech billionaire who built a dynasty on fear and control-emerges. He has developed a targeted airborne virus that specifically activates the crime genes in anyone who carries them, threatening to plunge the world into chaos and justify his final power grab.

Briar and Marcus, now leaders in the Zero-Zone, are the only ones with the expertise to counter the virus. They blend action-packed sequences with a high-stakes bio-thriller, culminating in a raid on the billionaire's floating fortress.

In the dramatic conclusion, Briar and Marcus must confront their own genetic destinies. They save a world that judged them by their DNA, proving that free will and love are the strongest forces in the universe. They find their happily ever after, not in a perfect city, but in the free and wild Zero-Zone they helped build.
