A secret government unit is formed under the oversight of Adam Harrison, famed paranormal investigator. The six members he's gathered know a little of the otherworldly—each has honed a psychic talent of their own. Jackson Crow, part English, part Cheyenne, heads the group. Haunted by his experience with an ancestral ghost who saved his life as a child, and the recent murders of two previous teammates, Jackson can't tell if Adam's demoted him or given him an extraordinary opportunity.
