perfect [adj.] - conforming absolutely to the description or definition of an ideal type
It is the word she practically grew up with. Little did she know that it was literal.
Isabelle is flawless, and is considered the ideal specimen of human kind. Never being in any way ill, her untainted genes can be used in so many ways; anti-aging cosmetics, curing cancer, all in all, to make money. Many people crave her, and it's a part of human nature to crave what you can't have.
This is Isabelle's story. She has learned the hard way, that perfection comes with a price. A heavy one.
