Zoe Maisey is a seventeen-year-old musical prodigy with a genius IQ. Three years ago, she was involved in a tragic incident that left three classmates dead. She served her time, and now her mother, Maria, is resolved to keep that devastating fact tucked far away from their new beginning, hiding the past even from her new husband and demanding Zoe do the same.

Tonight Zoe is giving a recital that Maria has been planning for months. It needs to be the performance of her life. But instead, by the end of the evening, Maria is dead.

In the aftermath, everyone—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.
