The next world war won't be fought with missiles. It will be fought with money. Marcus Thorne, a disgraced analyst known as "The Auditor," was exiled to the sub-basement of the U.S. Treasury for flagging systemic vulnerabilities. Now, his proprietary anomaly detection system screams a Level 5 Critical Alert: a $50 billion transaction has just exposed the West's greatest vulnerability. The Competitive Social Democratic Republics (C.S.D.R.) have launched the International Monetary Unit (I.M.U.), a new global currency backed not by gold or debt, but by The Population Protocol-a chilling algorithm that weaponizes demographics to dismantle the debt-based economies of the West. This is a bloodless coup, a financial war waged with chilling precision. With the world's financial system on the brink, Thorne must race against the clock to find the flaw in the I.M.U.'s code before the C.S.D.R.'s brilliant architect, Dr. Anya Sharma, executes "Operation: Singularity" and achieves total global control. From the shadowy trading floors of London to the monolithic Nexus in New Harmony, Thorne must risk everything to inject a single line of code that could either save the world or plunge it into financial chaos. The war for the future of society has begun, and the ultimate audit is about to be executed.
