My Bully’s Father by Jordan Silver

Jenna, or Geneviève as she’d been born, was a rather unfortunate child. Born to a single mom on the lower end of the poverty ladder, she was a homely little thing when she was a child. By the time she was twelve, she was about forty pounds overweight on top of the worst acne outbreak known to man. Her existence was not helped any by the presence of her bully and nemesis. Not only was this bully the only daughter and child of the town’s wealthiest man, who spoiled her for all the world to see, but the mother was not much better than the child. These two made Jenna’s life more of a misery than the poor child could handle.
Years later, things have changed, and a new Jenna returns to the town where she’d had her worst experience, but no one recognizes her, not even her worst enemy. And that’s just how she planned it. She’s here to destroy her nemesis cushy life, and seduce her newly divorced father.
