Ground Zero

A Bioterrorism Espionage Thriller

The next world war won’t start with bombs. It’ll start with a cough

When the director of Germany’s top weapons institute is blackmailed into stealing a classified bioweapon and handing it over to a paramilitary syndicate, NATO is plunged into crisis. The stolen pathogen is designed for rapid deployment, mass infection—and political collapse.

Enter Major Sophie Decker and her black-ops strike unit Department 89. Her mission: locate the bioweapon, eliminate everyone involved, and prevent a modern apocalypse.

But the deeper Decker digs, the clearer the truth becomes: this isn’t just a rogue operation. It’s the opening move in a global power shift—engineered through bioterrorism, blackmail, and mass destabilisation.

Perfect for fans of Mark Dawson, Kyle Mills, and Brad Thor — Ground Zero is a high-stakes bioterrorism thriller where one woman stands between civilisation and collapse.
