Puppeteer

Welcome to a world of heartbreak and broken dreams. At first glance, it is very like our own, but closer inspection will reveal those few special defects. The puppets. Born with a genetic mutation, they are nearly indestructible, only fire being capable of piercing through their skin. This superpower, of sorts, makes them highly feared by the rich and powerful, and so, they are forced into labor. The poor treat them like objects. The rich are worse. If anyone else, it'd be considered inhumane. But then again, to the rest of the world..
They aren't human.

Meet the two star crossed lovers: Jack and Lynn.
Lynn has spent all her life hiding her true feelings to keep herself safe. Then she meets Jack, a human who can make her laugh. For a short time, Lynn is the happiest she's been.

Of course, this isn't a love story.
And happiness.
Never.
Seems.
To.
Last.
