From a woman who has been there and back, the first inside look at the devastating effects evangelical Christianity's purity culture has had on a generation of young women - in a potent combination of journalism, cultural commentary, and memoir.

In the 1990s, a "purity industry" emerged out of the white evangelical Christian culture. Purity rings, purity pledges, and purity balls came with a dangerous message: girls are potential sexual "stumbling blocks" for boys and men, and any expression of a girl's sexuality could reflect the corruption of her character. This message traumatized many girls - resulting in anxiety, fear, and experiences that mimicked the symptoms of post-traumatic stress disorder - and trapped them in a cycle of shame.

This is the sex education Linda Kay Klein grew up with.

Fearing being marked a Jezebel, Klein broke up with her high school boyfriend because she thought God told her to, and took pregnancy tests though she was a virgin, terrified that any sexual activity would be punished with an out-of-wedlock pregnancy. When the youth pastor of her church was convicted of sexual enticement of a 12-year-old girl, Klein began to question the purity-based sexual ethic. She contacted young women she knew, asking if they were coping with the same shame-induced issues she was. These intimate conversations developed into a 12-year quest that took her across the country and into the lives of women raised in similar religious communities - a journey that facilitated her own healing and led her to churches that are seeking a new way to reconcile sexuality and spirituality.

Sexual shame is by no means confined to evangelical culture; Pure is a powerful wake-up call about our society's subjugation of women.
