Tunnel Rat

Milo lives in a steel cave within a man-made mountain of steel and concrete. He spends his days repairing the machinery that keeps the habitat livable and tinkering with the prosthetics that help his twisted body move about through the small tunnels and air shafts that are his world. He's as much a piece of discarded machinery as the equipment he keeps running. An escaped lab experiment living in a hole. Given a chance at being someone different, will he become a hero and live in the sunlight?

Book 2 of this unique spin on LitRPG featuring an unusual MC you can't help but root for. Featuring plenty of humor, action, thievery, ninja abilities, a detailed world and System, science skills, magic tinkering, item invention, and more originality than you can shake a rat tail at!

Milo needed a break from fighting giant monsters, insane wizards, and the constant gang warfare of Shadowport. The World Boss he'd accidentally woken up was dead. The annoying wizard who'd captured him was lost in the void along with his annoying little dragon, his airship stolen, and his library destroyed. That left him free to go exploring in the dark tunnels beneath the city. He'd thought that as a were-rat he was unique, but he's heard a rumor of a small town of ratkin living beneath the city and sets out to find it.
