Assistant D.A. Alexa Hamilton has just been handed the kind of case that makes careers: the trial of accused serial killer Luke Quentin. Sifting through mountains of forensic evidence, Alexa relentlessly builds her case and prepares for a high-stakes trial, until threatening letters throw her private life into turmoil. The letters are addressed to Alexa's beautiful 17-year-old daughter, Savannah, who Alexa has raised alone since her painful divorce years before. Alexa is certain that Quentin is behind the letters - and that they are too dangerous to ignore. Suddenly Alexa must make the toughest choice of all - and send her daughter back to the very place that Alexa swore she would never return: to her ex-husband's world of southern tradition, long memories, and the antebellum charm of Charleston.
