Did you ever see the movie "Romancing the Stone" with Michael Douglas and Kathleen Turner? Kathleen Turner plays a romance author who gets caught up in an adventure and eventually romance via her kidnapped sister. In it she's kind of mousy and a bit uptight and the hero is a kind of soldier of fortune/ne'er do well. It's a fun movie and it reminds me of the whole turnabout story that you have here.

Now, if you want a true turnabout romance style story then you need to find "A Brother's Price" by Wen Spencer. In that book the population is mostly female and men are locked away and betrothed to entire families of women for breeding purposes with high stakes involved.
