Growing up in Liberty Lake, Minnesota, Mary was chubby, awkward, and smart. 3 years later, “Ivy League Mary” is back—a thinner, cynical, and restless failure. Kicked out of Cornell at the beginning of senior year, she won’t tell anyone why. When beautiful, magnetic Olivia Willand, a rising social media star goes missing, Mary—like the rest of Liberty Falls—becomes obsessed. Best friends in childhood, Mary and Olivia haven’t spoken in years. Everyone admired Olivia, but Mary knows that behind the Instagram persona hid a willful, manipulative girl with sharp edges. She also believes that her disappearance is tied to another missing person—a 19-year-old Black girl named DeMaria Jackson who no one else seems to care enough about. Who was the true Olivia Willand, and where did she go? What happened to DeMaria? As Mary delves deeper into the lives of the two missing girls, old wounds bleed fresh and painful secrets threaten to destroy everything. Maybe no one is really a nice girl, after all.
