Growing up in Liberty Lake, Minnesota, Mary was chubby, awkward, and smart; a scholarship to an Ivy League school was her ticket out. Three years later she's back-- thinner, cynical, and a restless failure. Kicked out of Cornell at the beginning of senior year, she won't tell anyone why. When Olivia Willand, a rising social media star, goes missing, Mary becomes obsessed. Best friends in childhood, Mary knows better than anyone that behind the Instagram persona hid a willful, manipulative girl with sharp edges. She also believes that the disappearance is tied to that of nineteen-year-old DeMaria Jackson, whose disappearance has gone under the radar. -- adapted from jacket
