College freshman Grace Tang never meant to rewrite the rules of love. She came to college to move on from a grief-stricken senior year and to start anew. So she follows a predictable routine: Attend class, study, go home and visit her dad every weekend. She doesn't leave any room in her life for outliers or anomalies. Then, Grace comes up with an algorithm for her statistics class to pair students with their perfect romantic partners. Though some people are skeptical, like Julia, Grace's prickly coworker, Grace is confident that her program will take all the drama out of relationships. That's why she keeps trying to make things work with her match, a guy named Jamie. But as the semester goes on and she grows closer to Julia, Grace starts to question who she's really attracted to.
