I had my idea for a series and identified the heroes. Now I had to pick the heroines, after all, these are romance novels - there must be both a hero and a heroine to make the circle complete.
So how do you choose a heroine? Good question. My heroines (in all my books not just Devils on Horseback) tend to be tough, outspoken, sassy dames who basically don't take crap from anyone. They're not all the same - some are tougher than others - but I don't write any TSTL (too stupid to live) weeping fools that you want to strangle.
