a harrowing and fascinating tale of apocalyptic obsession and murder. Leah Sottile leads us down every head-shaking twist and turn of the case, an expert guide to the dark tributaries of religious extremism that run closer to the American mainstream than we'd ever like to believe."―Jess Walter, American author of Ruby Ridge

On the heels of the sensational murder trial and shocking verdict, WHEN THE MOON TURNS TO BLOOD examines the culture of end times paranoia and a trail of mysterious deaths surrounding former beauty queen Lori Vallow and her husband, grave digger turned doomsday novelist, Chad Daybell.

When police in Rexburg, Idaho perform a wellness check on seven J.J. Vallow and his sister, sixteen-year-old Tylee Ryan, both children are nowhere to be found. Their mother, Lori Vallow, gives a phony explanation, and when officers return the following day with a search warrant, she, too, is gone. As the police begin to close in, a larger web of mystery, murder, fanaticism and deceit begins to unravel.

Vallow's case is sinuously complex. As investigators prod further, they find the accused Black Widow has an unusual number of bodies piling up around her.

WHEN THE MOON TURNS TO BLOOD tells a gripping story of extreme beliefs, snake oil prophets, and explores the question: if it feels like the world is ending, how are people supposed to act?
