The Insider

Sooooo I'm really bad at descriptions.
So basically it's about a girl names Kitañya Petrova and she's a Red.
In this World there are 3 types of people. Reds and Golds, and Silvers. Golds are the royal people. The people with the power. Silver, The aristocrats, The generals. Those that control. Those with Silver Blood.
Then there are the Reds. They're the workers basically. They get their hands dirty and do manual labor and work hard. But don't have all the extravagance and luxuries the Silvers and Golds do.
Having a job working for a silver as a cook, maid, butler, etc. would be an immense honor for a Red. Even more so if they were a Gold. But even so, there are still some silvers that work for other silvers and Golds. But because they're a silver, it's be different for a Silver Maid and a Red maid.
Don't bother making it seem like a Gold even actually works as servants and common folk.
All details of the work. Along with pay, it's different working as a silver.
But hey, when a Red is suddenly thrusted into the World of Silver and Gold, she has to do everything in her fighting spirit to fit in or those she cares about will die.
