USA Today bestselling author Charles Wilson delivers a cutting-edge scientific thriller based on real-life experiments at improving human intelligence currently underway in both government and private circles. Imagine a computer chip no bigger than the tip of a pencil. This chip, if implanted in a human brain, could give someone encyclopedic knowledge, lightning-fast reflexes and superior learning skills. In a remote military hospital in Montana, an experiment is being performed: implant the chip into the brains of five volunteers. These volunteers, four men and one woman, are all serving life sentences in prison. The experiment works...but the five criminals escape. One young doctor is pulled into the intrigue by the baffling murder of his medical school mentor. Can this one doctor stop the conspiracy of five powerful opponents... whose driving desire is absolute and total control?
