In October 2014, young Miranda Barbour and her husband, Elytte, were sentenced to life imprisonment for the brutal murder of Pennsylvania politician Troy LaFerrara--a middle-aged man Miranda met through Craigslist. The victim's bloody body had more than 20 stab wounds, and marks on his neck indicated he had been strangled.

What caused a teenager with the quiet demeanor of the girl next door to commit such a heinous crime? This book will reveal exclusive new information. In prison interviews with coauthor Francis Scarcella, the only reporter Miranda spoke with for more than a year, she claims to have killed not just LaFerrara, but at least 22 other people, when she says she stopped counting. Allegedly, she committed her first murder when she was a preteen and a member of a satanic cult. And the total number of her victims may be close to 100.

Is this true or is she a psychopathic liar--a serial-killer wannabe? The police continue to investigate.

Based on many hours of interviews, personal diaries, and letters, this true-crime story is a shocking page-turner, revealing the disturbed, criminal mind of a woman who admits to "a monster inside of me. It's always there."
