A Beast Cannot Feign: Sci-Fi your mother won't show you

Half-aliens prowl the Earth, defying our laws, banging our women and laughing at our taxes. I mean really laughing.

Now she's shopping for a little patch of Earth to call, home, say, 10,000 square miles. Every right-thinking Human welcomes that idea like a fart at a wedding. A half-alien colony would really need defending, so they've hired the very human Tom Pine to build robotic sentries, beneath Luci Dark's watchful eye. What could possibly go wrong?
