The doctor doesn't believe the waking nightmares. The physiotherapist wants her old life back. The NSA agent has very little time to solve the mystery before we all succumb. The stakes are nothing less than human extinction.

From the author of This Plague of Days comes a unique mix of science fiction and the paranormal.

At a resort hotel in Dubai, bodies are found crushed beside their beds. A village in France fills with corpses. Each night, the terror builds. As nightmares become reality, lucid dreaming may be the only way to fight the threat invading our minds.

Leave the light on. You'll be up all night, turning pages, afraid to sleep.
