From New York Times best-selling true crime author John Glatt comes the devastating story of the Turpins: a seemingly normal family whose dark secrets would shock and captivate the world.

On January 14, 2018, a 17-year-old girl climbed out of the window of her Perris, California home and dialed 911 with shaking fingers. Struggling to stay calm, she told the operator that she and her 12 siblings - ranging in age from two to 29 - were being abused by their parents. When the dispatcher asked for her address, the girl hesitated. "I've never been out," she stammered.

To their family, neighbors, and online friends, Louise and David Turpin presented a picture of domestic bliss: dressing their 13 children in matching outfits and buying them expensive gifts. But what police discovered when they entered the Turpin family home would eclipse the most shocking child abuse cases in history.

In the first major account of the case, investigative journalist and author John Glatt delves into the disturbing details and recounts the bravery of the 13 siblings in the face of unimaginable horror.
