Dreamers

She was completely unresisting as the huge, calloused hand clamped over her mouth and pulled her head back. The last thing she saw was the devil himself standing over her before the blade slashed a long, smooth arc across her throat with such force it grated across her cervical vertebrae, and everything faded to black.
Wilson Cole is having enough difficulty distinguishing between what's real and what's imagined, but he's inclined to believe the experts when they tell him his Dreamworld is just a figment of his imagination. But his nightmares reach a whole new level after a run-in with the 'imagined' Greenspite and the subsequent murder of his closest friend.
To a veteran cop like Alex Gumbold there's nothing new under the sun, until he meets Wilson Cole and everything he believes is turned on its head. Cole is the common denominator and prime suspect in the Sleep Institute murders, but as the body count rises he discovers how little his 37 years as a policeman have prepared him for the ensuing revelations, as he's torn between enforcing the law and discovering the truth.
