It has been ten years since twenty-one-year-old Charles MacKenzie Jr. ("Mack") went missing. He does make one ritual phone call to his mother every year: on Mother's Day. Mack's sister, Carolyn, now twenty-six, is a law school graduate. She has endured two family tragedies, yet she realizes that she will never be able to have closure and get on with her life until she finds her brother. So this year when Mack makes his annual Mother's Day call, Carolyn interrupts to announce her intention to track him down, no matter what it takes. Carolyn's pursuit of the truth about Mack's disappearance swiftly plunges her into a world of unexpected danger and unanswered questions. Can the police possibly believe that Mack is not only alive, but a serial killer, a shadowy predator of young women? Was Mack also guilty of the brutal murder of his drama teacher and the theft of his taped sessions with her?
