Friend or Foe — Jennifer Denys

Despite a strong attraction, Gina Mitchell is constantly at loggerheads with work colleague Dan Rayner. However, the hero of the book she is writing-her first ever-is based on him, recreating erotic sex scenes from the movies. When Dan finds out exactly what she is writing, this gives him the opportunity to tease her unmercifully. The queen of insults, Gina gives as good as she gets, but gradually Dan becomes interested in her writing and Gina starts to lean on him for support as she experiences the trials of getting her story published. Their relationship goes to a new level when this starts to involve practicing some of the scenes including on a piano and in a car, the growing chemistry allowing them to become more adventurous. But will the "just good sex with a friend" go any further, or will they drop back to their old insults?
