"Ellie Mack was the perfect daughter. She was fifteen, the youngest of three. She was beloved by her parents, friends, and teachers. She and her boyfriend made a teenaged golden couple. She was days away from an idyllic post-exams summer vacation, with her whole life ahead of her. And then she was gone. Now, her mother Laurel Mack is trying to put her life back together.
