IS THIS REALLY THE END?

Rose Everhart never really had it easy her father left at the mere sight of her which destroyed her mother, and well the mother thought the wisest thing to do was to leave her at an orphanage.

It's been a few years and well rose has turned into a 11 year old girl with her found brother which she met on her eighth birthday he's name is max and he's two years older then her and when I say they love each other more then words could speak

So what happens when the world suddenly comes to an end and the two siblings get separated from each other.

Will ROSE make it in this world while trying to find her brother or will she die along with the new fucked up world.
