Hell Breaks Loose

Annaliese was a pretty ordinary girl, with a brother and sister, Price and Mia, who were two years older and were twins, their mother and a step father, after their real father decided to run away when Anni was four. Since then, Anni's parents forbid her and her siblings to talk about it, leaving them completely clueless as to what happened, forcing them to continue their lives as if nothing had happened, but suddenly, Anni, Price and Mia are ripped away from their lives, only to be thrown into a new one. A completely different one, and it wasn't Anni's fault that she was in the middle of a maths class when Hell decided to break loose.
