An angel's nightmare

It's Piper's senior year of university and Piper and her friends are more than excited to get out into the big, wide world. Each thinks they know who they are and what they want, but do they?

When a earthquake strikes, the whole world is shook and nothing is left the same...

The most good people become bad and the most bad becomes good. So when Piper becomes bad can her friends save this Angel from her nightmare?
