I almost didn't finish this, then realized that if I don't finish it, I can't give it bad review. It was bad. The basic plot setup is that a woman asks her brother to seduce a virginal young woman because she's jealous. The "hero" does it, but only because he wants to anyway. How romantic. 
 The historical/social stuff was way off. This was supposedly a Regency concerning aristocrats. A man introduces himself to a marriageable young woman. Young woman accepts a gift of jewelry from a man. (he gave her a pearl necklace! No, really! He gives ALL his lovers a pearl necklaces, only he gives it to them by putting them into their vaginas first, because he's a sweetheart like that!). Everyone knows young woman is the mistress of this Marquess of Slutbag, but people still talk to her anyway. A mother pimps out her marriageable daughter to perverts not ONCE but TWICE, also expecting the hero to rescue her--but DOESN'T TELL HIM ANYTHING. WTF? I think maybe Hawkins could have pulled off something like this if she made her heroine of a lower class, or did anything to acknowledge the vileness of the mother, or at least stage something satisfactorily awful to happen to the villainess...but no. This was really not worth the time or the discounted price.
