Book excerpt: Tad McGreevy has a power that he has never revealed, not even to his life-long best friend, Stevie Scranton. When Tad looks at others, he sees colors. These auras tell Tad whether a person is good or evil. At night, Tad dreams about the evil-doers, reliving their crimes in horrifyingly vivid detail. But Tad doesn't know if the evil acts he witnesses in his nightmares are happening now, are already over, or are going to occur in the future. He has no control over the horrifying visions. He has been told (by his parents) never to speak of his power. All Tad knows is that he wants to protect those he loves. And he wants the bad dreams to stop.
