Book review: Amity and Sorrow, By Peggy Riley

God, Sex and Farming was the working title of Riley's page-turning debut about a mother's escape from a polygamous end-of-the world cult.

In the wake of a suspicious fire, Amaranth grabs her two daughters and flees the burning compound, leaving behind her husband and his other 49 wives.

Finding themselves somewhere in the Oklahoma Panhandle, the young sisters, Amity and Sorrow, experience the outside world for the first time: electrical outlets, Doritos and TV.

Riley examines the horrors a believer can inflict on his own progeny.
