The Complete Wasteland Road Knights - Magi Saga Collections, #4

Deep in the wasteland, two strangers meet. A nomad and a slave. And the Road Knights are born. Surviving in the wastes in his V8 Charger, Nero sells his skills as a gun for hire. He fights raiders, mutants and zombies in return for food. He's a survivor. Nothing more. As a slave at the Watchtower, Nyx's life is tough, and brutal. She trains with her mothers blade, dreaming of freedom. But Nyx has a secret, one her master can never know.
When Nero visits the Watchtower, events soon spiral out of control. Now, thrown together, they must fight through fire and blood for their very lives. From the chaos, a legend is born. The Road Knights.
