Frankenmice

Beneath New York City, generation after generation has grown smarter, more organized, and more ambitious. Hidden inside tunnels, walls, abandoned stations, and forgotten infrastructure, the mice have built a civilization of their own, complete with laws, factions, technology, and a growing hatred of the species that created them. When strange thefts, disappearances, and impossible messages begin surfacing across Manhattan, Detective Petra Sloan is drawn toward a secret that could change humanity forever.

What waits below the city is far more dangerous than an infestation. It is a kingdom that has spent years studying us, learning from us, and preparing for the day we finally discover it. Now that day has come, and the question is no longer whether the mice can survive humanity, but whether humanity can survive what it created.
