"Delirium" bestselling author Lauren Oliver presents a gripping tale of two sisters whose lives have changed inexorably since a freak accident. Dara and Nick used to be inseparable, but that was before their estrangement - before the accident that scarred Dara's face. When Dara disappears from her birthday celebrations, Nick thinks her sister is playing her violent games again. Only after the disappearance of another girl - nine-year-old Maddy - does she become convinced that the disappearances are connected. Now Nick must plunge into an intriguing world of loss, suspicion and find not only her sister, but herself.
