'The crash of a rock against glass smashes Cassie’s familiar world. The air outside Arcadia is poisonous, or so she’s been told. Is it better to risk a quick death outside the dome or to suffer a slow decline within? Paul has been told the old dome contains biological hazards that threaten the lives of the people of Rangelands. But Cassie is just an ordinary girl, or as ordinary as any girl can be who has lived her whole life locked away inside an ancient dome. With all the obstacles thrown into their path, it seems impossible Cassie and Paul will find a way to be together. But sometimes the power of love can surprise us all. '
