Knock Out by Catherine Coulter

Seven-year-old Autumn Backman needed a hero. When she saw Special Agent Dillon Savich on TV after he'd brought down bank robbers in a Georgetown bank, she knew she'd found him.

She called Savich, but she didn't use the phone...

Ethan Merriweather, sheriff of Titusville, Virginia, a small mountain town near the Titus Hitch Wilderness, goes looking for a missing little girl. Soon after he finds her, Ethan realizes that Autumn has brought him a huge problem - a relentless madman who has the ability to control others simply by looking at them. And the madman is after her and her mom.

It's a race to stop the madness, or the madness will destroy them all...
