I loved this book when I read it as a teenager, and found myself horrified by the themes as an adult looking back, especially as of all the books I read then, this one stuck out and influenced my views of marriage, sexuality, and relationships in ways it was not equipped to do, not for the good anyway.
Here's what I wrote about it in a journal a few years ago:
"The "explorer" is a man who makes a living as an heretical archeologist hunting down ruins and then incongruously selling artifacts to collectors...or maybe it was selling books about his adventures. In any case, he was a hedonist, a dashing, exciting, romantic figure, and gone for most of the book outside of the country, much less the state. The book, abnormally for a romance, opens with the man and his to-be love getting married a week after meeting at a wedding. The beginning chapters are full of dialogue between them - actually, the majority of the book is between the man and woman, with very few exceptions - about his past sexual adventures and his opinions about marriage. He is a sexual libertine, of the opinion that a man and woman who are not otherwise attached have nothing to be ashamed of in enjoying each other sexually.
The woman, meanwhile, is a repressed Virginian belle of the highest sort. She refuses to even consider sex before marriage, and finds herself incapable of even talking about sex, until she finally (you know, after a few days, given the speediness of the courtship) admits that her mother told her horror stories about abuse and is therefore petrified of sex. The man assures her that sex is much more fun than that and proceeds to tell her that he'll never hold her down again after the first time - presumably because there's no way to show her that sex doesn't have to be scary or violent and can be quite desirable and pleasurable even for women other than physically forcing her, albeit with her consent."
