Sarah is a hard working student. But she's lonely. Having been betrayed years ago by her former childhood best friend--the same guy she'd a massive crush on from about the ages of ten to seventeen--she decided to forego a social life and work her tail off in university until she got accepted to the best medical school in the country. Now she's about to start living her lifelong dream. But sitting in her dorm room the night before her first day of med school, she finds out that none other than Ozzy Jones is in her med school class. Ozzy and Sarah used to be inseparable until he became Mr. Gorgeous and Popular in high school and discarded her in a spectacularly humiliating fashion. Losing Ozzy left a hole in Sarah's life that she's never quite been able to fill, but at least she's (mostly) put her teenage heartbreak behind her. Or so she thought. Because now, not only is Sarah facing new academic challenges in medical school, she's forced to steel her guard and at least try to pretend that Oz doesn't affect her like no one else ever has. Neither Oz nor the universe make that a simple task.
