Malcolm Reed moved to Seattle to escape a failed marriage and a daughter who won't return his calls. As a pest control technician, he's seen thousands of rats. But the ones beneath this city are different. They don't run. They watch. They coordinate. They remember.
When a biotech lab's most ambitious experiment escapes containment, Seattle's underground becomes the breeding ground for something unprecedented — a rat colony engineered with human neural tissue, evolving faster than anyone predicted. They've built a network beneath the city. They've mapped the power grid, the water system, the people. And they've developed a taste for human brain tissue.
Now Malcolm's daughter Casey has arrived for Thanksgiving. The city is under siege. And the bite on her wrist is already turning dark.
Armed with a flashlight, a decade of extermination experience, and a growing sense that none of it will be enough, Malcolm descends into the Seattle Underground to face an intelligence that doesn't just rival humanity — it's already surpassed it.
GNAW is a relentless, grounded horror novel about an ordinary man fighting an extraordinary threat — and losing.
"The rat's eyes caught the beam of my flashlight, twin rubies glowing in the darkness. It didn't scurry away like they usually did. It watched me. Assessed me. I swear to God it smiled."
