A perfect weapon. A foolproof plan. And one man standing in the way. There's a new weapon on the world stage. Silent. Invisible. It boils its victims from the inside out and leaves no trace. A perfect assassination tool. A massacre in Pittsburgh was just a demonstration. A proof of concept before the weapon is scaled up. And the rogue faction behind it have far greater ambitions. They don't care if they provoke a war between the United States and China in the process. In fact, that's the point. Jason Trapp's investigation into the Pittsburgh attack takes him from a terrorist-run mine in Nigeria to the rain-slicked streets of London, with assassins waiting at every turn. They should have killed him when they had the chance. Now it's too late.
