Tunnel Rat

Milo lives in a steel cave within a man-made mountain of concrete. He spends his days repairing machinery and tinkering with the prosthetics that help his twisted body navigate the small tunnels that are his world—as much a piece of discarded machinery as the equipment he maintains. Given a chance at being someone different, Milo may become a hero. But there are secrets buried in the ground—ancient mysteries left by races that delved deep and stayed below. Maybe only a tunnel rat can discover them.

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 giant monsters, insane wizards, and constant gang warfare in Shadowport. With his enemies dealt with, he sets out to find a rumored town of ratkin living beneath the city. Limburger Hollow welcomes him warmly—and then promptly tosses him into fighting pits, wizardly duels, and competitions between local assassins who love to play a game called Surprise. Milo loves a challenge. If he doesn't know all the rules, he'll make up some of his own.

Milo is back, causing trouble in the game world of Genesis—and beginning to suspect it might be more than just a game. A trip to an underground market leads to a few new friends, which proves timely as corporations and organized crime move into his home. Family matters, he learned that in Limburger Hollow, and Milo has a new family to protect. His old family—who he thought were dead—are also looking for him. And the world's largest AI, Wally, wants to know about all of them.
