Challenge Prompt - Sci Fi

[JamesSavik]

I'd write this story, but I'm writing too many as it is.

You've probably seen John Carpenter's 1988 movie They Live. If you haven't, scurry out, find a copy and enjoy!

This movie gave me an idea that would make a great story.

Aliens are invading and slowly subverting the world. We can't see them. Due to puberty hormones, only some kids ages ~10-14,  can see them.

With that premise, let the games begin.
