They call themselves the Replete, powerful corporate leaders whose greed has become a need they would do anything to satisfy. They're making billions with a scheme so grand, so insidious, that stopping them could upset the entire economy. Dr. Roger Morgan is a rare expert in emergent systems-birds forming flocks, drivers forming traffic, investors forming a market. In the right hands his powerful methods help optimize our world. In the wrong hands, those methods could manipulate people, events, even industries. When Roger meets Amber it is anything but chance. She knows that the death of his old classmate is connected to the death of her friend, and that the murderer is now after her and Roger. They don't know who it is and they don't know why, but each new clue tells them the plot is even bigger than they thought. And if they don't find the murderer soon, the murderer will surely find them.
