It's the last day of school, and everyone is excited for the big summer leading up to our senior year. I was too... until my heart was ripped out of my chest. As if getting dumped wasn't bad enough, I'm forced to endure the humiliation of witnessing my ex-boyfriend flaunt his new girl - who also happens to be my now ex-best friend - all over town. Double whammy. Now I'm the pathetic ex-girlfriend left gutted, heartbroken, and nose deep in a bucket of ice cream. I'm doomed to spend the summer sulking over a guy who thought I was predictable and bad in bed. So, when I get an offer guaranteeing me some well-deserved payback, of course I'm going to take it. Besides, the plan is simple. Pretend like I'm dating Ryder, the town's popular bad boy, and make my ex wallow in a pit of jealousy and regret. It's perfect. I mean... what could possibly go wrong?
