Public Secrets

Complex relationships among a believable ensemble of characters give Roberts's ( Sweet Revenge ) new romantic thriller much of its appeal. Emma McAvoy, daughter of a British rock star, is only six years old when her infant half-brother Darren is murdered in a bungled kidnapping attempt. Emma, the only witness, remembers little of that night, and while investigators determine that someone close to the family was involved, the case is never solved. Nagged by fears for her safety, Emma's father has her trailed by a bodyguard whenever she is not closed away in a private school. But as she grows up, neither guards nor a loving father can protect her from the nightmares and feelings of guilt that torment her. Nor can they shield her from Darren's murderers. Although it concludes with a satisfyingly gripping finale, the mystery is more a recurring element than a driving force, as the story explores the members of McAvoy's rock group, Emma's devotion to her father (who bought custody of Emma from her abusive, alcoholic mother), her destructive marriage and the father-son detective team whose dedication to the McAvoys and this case lasts more than 20 years.
