This book was set at a boarding school where the girls and the teachers are affected out of nowhere with this virus known as Tox that causes different things to happen to their bodies. Many of the girls and teachers pass away and the school is put into quarantine. They are confined to the Raxter School of girls and are separated from the outside world. Hetty, Byatt, and Reese are a group of girls that have chosen to stick together. When Byatt is taken away from their group after another wave of Tox hits, Hetty will do anything to save her. They find that nothing is at it seems and that their life is just one big experiment that has went wrong. I loved that this book has so many genres tied into one and that it is so deliciously different from anything else I have ever read before.
