Knee Deep Vol. 1: Book One

Two hundred years in the future, the survivors of an environmental cataclysm took refuge underground. Their descendants now live in a literal sewer, the bowels of a subterranean city--an abandoned future utopia--that was never completed. These sewerfolk, a collection of scavengers, misfits, bandits, renegades, and mutants, eke out a living in this underground maze of tunnels and canals.
Life is hard enough, but an overzealous mining company, PERCH, wants to get their claws on this new underground frontier. And they won't hesitate to bulldoze any sewerfolk that get in their way.
Caught in the middle is Cricket, a young girl desperately searching for her family that fled underground. Join Cricket as she explores this savage new world to find her parents and unlock the secrets of a past long forgotten in the three-part graphic novel series, KNEE DEEP.
