I admit it – I am fascinated with polygamy. I can’t figure out how it could possibly work for any family. Ever. This is why I devoured “Big Love” and “Sister Wives.” The Sound of Gravel is a memoir of a girl growing up in a polygamist sect in Mexico. Ruthie was the thirty-ninth of her father’s forty-two children. Her family lived in poverty and she was abused by her step-father. It’s a depressing story, but one of hope as well. I read the whole book in a few hours because it was so readable and interesting. The author didn’t get into the weeds about the sect itself, but focused on her own day-to-day experience. I really wanted to find out how she escaped this life and what her adult life is like. I didn’t get much of this at the end, but the story carried itself anyway.
