Books like this one are few and far between, but a really important contribution to the conversation in a sex-saturated culture where most people, Christians included, have lost sight of the honour and dignity of the celibate life.
Taylor's book is academic in style, so not everyone is going to find it readable. It also references material that some readers may find disturbing.
Something I'd love to see from this author is a more readable summary of her findings, aimed towards helping churches rediscover a way to honour celibate singles and teach about the value of abstinence without second guessing themselves.
(Side note: Taylor uses the term 'chastity'. I tend to prefer to talk about 'celibacy'. I feel that one makes too much of virginity in and of itself, whereas with the other it's not about whether or not one has ever 'fallen' but rather about how one chooses to live, even if one struggles or falls and has to get back up again.)
Bottom line: An important book, but not something that I'd recommend to most readers unless they're really keen on the topic and up to the challenges of this style of writing.
