I have a handful of books on my shelves dealing with relationships. Some are very cookie-cutter-ish. So predictable they leave you wondering why you bought them in the first place. (Thank goodness I didn't buy He's Just Not That Into You.) Others are more personal; telling the stories of single women. Others are more faith focused; exploring the Biblical basis for relationships, gender and marriage.
On that note, Jan has two recent posts one the topic: Pre-Marital Adultery and Sex and the Single Girl.
