When Cassandra was a girl, growing up in a racially diverse middle-class neighborhood in Baltimore, her best friends were all black: elegant, privileged Donna; sharp, shrewd Tisha; wild and worldly Fatima. A fifth girl orbited their world—a shy, quiet, unobtrusive child named Calliope Jenkins—who, years later, would be accused of killing her infant son. Yet the boy's body was never found and Calliope's unrelenting silence on the subject forced a judge to jail her for contempt. For seven years, Calliope refused to speak and the court was finally forced to let her go. Cassandra believes this still unsolved real-life mystery, largely unknown outside Baltimore, could be her next bestseller.

But her homecoming and latest journey into the past will not be welcomed by everyone, especially by her former friends, who are unimpressed with Cassandra's success—and are insistent on their own version of their shared history. And by delving too deeply into Calliope's dark secrets, Cassandra may inadvertently unearth a few of her own—forcing her to reexamine the memories she holds most precious, as the stark light of truth illuminates a mother's pain, a father's betrayal . . . and what really transpired on a terrible day that changed not only a family but an entire country.
