The rate of violent crime is on the rise, and nowhere is this more evident than in the state of Colorado. Amazing Grace, how sweet the sound, that saved a wretch like me... It's called Acute High-Altitude Neuropathic Dissociation—or, more commonly, Mile High Syndrome—and Dr. Ellis Randall Harding, a neurologist, is determined to understand why. For him, it's personal. He was there on September 24th, 1994 when a gunman walked into the library and started shooting. I once was lost, but now I'm found… The answer is locked inside the mind of a monster who shot and killed nine people in 1968. The problem is he's in a vegetative state and incapable of communicating with anyone, except for Dr. Harding, who has figured out how to utilize medical imaging technology to amplify and interpret the killer's brain activity. Was blind but now I see… But as Dr. Harding learns, there are some things that mankind was never meant to understand. Chief among them, the true nature of evil.
