Claire Tambers has watched those she loved being taken away from her and she never imagined she would have to choose the person who she would lose next. Nightmares of the car crash plagued her since it happened, only one year ago. Now, she's going to a local high school in her city and preparing to become the newest guardian at a secret high school. She is able to protect anyone, but some she cannot save because she has sworn to follow the Natural Order which dictates who is to live and die. A cruel responsibility that Claire must bear, but an important one to keep things in order. That is, until the day she finds out that her youngest brother, Ryan, is on the List of those who die. She knows what will happen to him and when, but the worst part is that she knows she cannot save him. Claire fights to find a way to save her brother, but in order to do so she would have to disturb the Natural Order which could cost more lives. And it did. She finds a way to save her brother, but as soon as that is done, her boyfriend's name appears on the List. With time running short, Claire must find a way to undo her mistake and now save the people she loves.
