Zoe Maisey, a seventeen-year-old musical prodigy with a genius IQ, is starting her life over after a tragic incident three years ago which left three of her classmates dead. Her mother, Maria, has resolved to keep that information tucked far away, hiding the past even from her new husband and demanding that Zoe do the same. Tonight Zoe is giving a recital that Maria has been planning for months. It needs to be the performance of Zoe's life. But instead, by the end of the evening, Maria is dead. In the aftermath, everyone--the police, family, Zoe's former solicitor, and Zoe herself--tries to piece together what happened. But as Zoe knows all too well, the truth is rarely straightforward, and the closer we are to someone, the less we may see.
