The Chosen have been warned. Powerful psychics across the globe have gotten the same eerie and insistent message: Go to Prosperity. Trapped in a nightmare they can't escape, the residents of Prosperity are killing one another, waking up with no memory of the monstrous acts they've committed - or the reasons why. Chief Deputy Katie Cole knows that whatever evil is afoot is beyond her expertise, and beyond the understanding of Sheriff Jackson Archer. The Special Crimes Unit is called in for its specific brand of investigation, to aid the Chosen as well as the once-peaceful mountain town.
