The Last Sword Maker by Brian Nelson

In the high mountains of Tibet, rumors are spreading. People whisper of an outbreak, of thousands of dead, of bodies pushed into mass graves. It is some strange new disease … a disease, they say, that can kill in minutes.
The Chinese government says the rumors aren’t true, but no one is allowed in or out of Tibet.
At the Pentagon, Admiral James Curtiss is called to an emergency meeting. Satellite images prove that a massive genocide is underway, and an American spy has made a startling discovery. This is no disease. It’s a weapons test. Chinese scientists have developed a way to kill based on a person’s genetic traits. But that is only the tip of the iceberg. The success of their new weapon proves that the Chinese are nearing “Replication”—a revolutionary breakthrough that will tip the global balance of power and change the way wars are waged.
Now the US must scramble to catch up before it is too late. Admiral Curtiss gathers the nation’s top scientists, including a promising young graduate student named Eric Hill who just might hold the missing piece to the replication puzzle. Soon Hill and his colleague Jane Hunter are caught up in a deadly game of sabotage as the two nations strive to be the first to reach the coveted goal. But in their headlong race, they create something unexpected … something the world has never seen and something more powerful than they had ever imagined.
The Last Sword Maker is an exciting globe-trotting thriller with unforgettable characters that depicts a haunting vision of the future of warfare.
