The Night of the Long Knives (Dover Doomsday Classics)

I was one hundred miles from Nowhere ― and I mean that literally ― when I spotted this girl out of the corner of my eye. I’d been keeping an extra lookout because I still expected the other undead bugger left over from the murder party at Nowhere to be stalking me.
Welcome to Deathland, a postapocalyptic nuclear desert where kill or be killed is the law of the land. The radiation-damaged survivors of this ravaged region are consumed by the urge to murder each other, making partnership of any sort a lethal risk. But when two drifters forge an uneasy truce, the possibility of a new life beckons.
Written by a multiple Hugo Award–winning author and one of the founders of the sword-and-sorcery genre, this novel-length magazine story first appeared at the height of Cold War paranoia. Fritz Leiber's thought-provoking tale addresses timeless questions about the influences of community and culture as well as the individual struggle to reform.
