The Eyes of Darkness - Dean Koontz

This is a tale to keep you awake all night...It's a year since Tina Evans lost her little boy Danny in a tragic accident, a year since she began the painful process of trying to rebuild her life. Then a shattering message appears on the blackboard in Danny's old room: NOT DEAD. Is it someone's idea of a grim joke? Or the tangible evidence of her tormented unconscious? Or something and more? The search for an answer, the search for Danny, demands a courage and endurance beyond any that Tina thought she possessed. Only her love for her son, her love for the one man who believes her, drives her on, through the neon clamour of Las Vegas nightlife, the sun-scorched desert, and the frozen mountains of the High Sierra. People die, coldly, brutally, as a buried truth struggles to surface. A truth so incredible, so frightening, so dangerous that its secret must be kept at the price of any life - any man, any woman and any child.
