El Presidio Rides North

On the verge of death by zombie in a public restroom, a young man is saved at the last minute by a shovel—and the intriguing man who wields it. A man who doesn't really want company, and definitely isn't interested in sharing names. But 'Mercury' also comes with an RV that doubles as a zombie-proof fortress, and almost any company is better than none—even if that company has a cute nickname for his nailgun, and inflicts him with the name 'Gaga'.
