Apocalypse Warnings only have to be true once

What a breathtaking opener, with our narrator literally running for her life, before we are thrown back to the beginning of how the story all started. We are in the typical new people in a school scenario, but this is one of those snobby upper class schools that are very hard to get into. They seem to have the same sort of bullies though, sniggering at each other in assembly, you just know you are going to hate them. The main character comes across quite well though so it is an easy read, and you want to know more, especially after the first few pages, i hope she escapes whoever is chasing her.
Had to use my points on this one to make sure i got a copy!
