Book excerpt: That nagging sense someone's watching. A feeling of impending doom before a disaster. Recognizing evil when you first meet it. Everyone experiences those strange vibes, odd tingles and unexplained hunches. But some people sense more. They're called Indigos. In The Indigo Files: Entangled, Ben Delano is recruited into a clandestine organization called The Knowledge Reserve (KnowRes), dedicated to controlling scientific information considered too dangerous to be released. Among the realities hidden by KnowRes is the existence of Indigos—people with psychic abilities. In his first case, Delano investigates a rogue group of Indigos infiltrating the U.S. government. His only leads: the oddball visions of a homeless clairvoyant and the twisted warnings of an incarcerated—and psychic—serial killer.
