Tatiana Miller is just a regular seventeen-year-old girl. She's finally a senior in high school, saved up enough money to buy up the car she's been slaving for all summer. Her parents bought her the puppy she's been asking them for since she was a kid (which was clearly an incentive to get Tatiana to stay home for college-which btw is never happening-but she appreciated the gesture.) Her lifelong crush is finally starting to notice her, her hair has been growing, her body is fitter, and with her best friend Stacy by her side, Tati will be unstoppable senior year! Or so she thought. Rumors of her mother's secret affair with notoriously bad boy Sebastian Bass's father begin to surface. And instead of clearing her name, her mother confirms them. Tati is ripped away from her perfect life and inserted to a new one faster than she could blink. She though living with the super hot rich bad boy in school would be a living nightmare, but when they team up to break their parents apart, she realizes he might not be so bad after all. But when the things Sebastian and Tati do come with some serious consequences, Tati reconsiders her decisions, including falling for her stepbrother.
