Relentless Koontz, Dean

Bestselling novelist Cullen Greenwich writes feel-good thrillers. He's never hurt anyone. So when literary critic Shearman Waxx publishes a savage takedown of his latest book, Cullen shrugs it off — until Waxx shows up at his house. Then follows him to a restaurant. Then tries to kill his family. What starts as a writer's bad review spirals into a surreal nightmare involving a sociopathic critic, shadowy government agents, and a conspiracy that rewrites everything Cullen thought he knew about reality. Koontz blends domestic suspense with sci-fi paranoia, delivering one of his most propulsive novels — equal parts terror and dark absurdity. The pacing is relentless (naturally), the stakes escalate fast, and the villain is genuinely unsettling. For fans of breakneck thrillers with a speculative edge, or anyone who's ever gotten a bad review and wondered what if.
