Quantum Night by Robert J Sawyer
Experimental psychologist Jim Marchuk has developed a flawless technique for identifying the previously undetected psychopaths lurking everywhere in society. But while being cross-examined about his breakthrough in court, Jim is shocked to discover that he has lost his memories of six months of his life from twenty years previously—a dark time during which he himself committed heinous acts.
Jim is reunited with Kayla Huron, his forgotten girlfriend from his lost period and now a quantum physicist who has made a stunning discovery about the nature of human consciousness. As a rising tide of violence and hate sweeps across the globe, the psychologist and the physicist combine forces in a race against time to see if they can do the impossible—change human nature—before the entire world descends into darkness.
Jim Marchuk is a brilliant psychologist who is level-headed and favors reason over emotion. He has developed a technique for identifying psychopaths which leads him to a startling discovery about humanity.
Quantum Night is a scientific thriller from the author of Flashforward (which was a short-lived tv show). Like Flashforward, this is heavy on the science, yet far-fetched enough to be science fiction. The characters are interesting and engaging. The story is even paced until the exciting, climactic ending. With plenty of mystery, suspense, and several huge twists – this will appeal to a large audience.
