I already pointed to these elsewhere today, so while its fresh in my mind:
For Women Only for the ladies

Its counterpart For Men Only for us guys.

I read both. Short books but to the point. Someone (TJ) years ago when I first joined here turned me on to them. I found these much better than Mars/Venus.

It's amazing how much common sense (to us men) is in FMO, but yet is news to all the women I passed this book onto.

In fact, if any women read FWO, I'd love to get a "review" to see how accurate (in your opinion) the author is.
