Cadence Archer arrives on Harvard's campus searching for answers about her brother, a schizophrenic genius who leapt from his dorm room window the year before. Though her choice to walk the same path as Eric threatens to break her family apart, Cady is determined to know why Eric killed himself. As Cady struggles under the enormous pressure that comes with being at Harvard, she begins to investigate her brother's life on campus. What was it that caused Eric to spiral into an irretrievable madness after he had been doing so well? Her prying turns up clues that grow increasingly sinister. And then, as her suspicions mount, Cady begins to hear voices herself. That's when the panic sets in. Does she share Eric's illness, or are these voices real? And if she listens to these ghosts, will they lead to her brother—and the truth—or will they lead her down a path of her own destruction?
