Save Her Life

The tears fall down the girl’s pale face as she desperately tries to struggle free from the ties around her wrists. The only sound in the room other than her muffled cries is the ticking of a clock. Her mother has less than one hour to find her alive. It’s been more than thirty years since Special Agent Sandra Vos’s twin brother was shot dead, an innocent victim caught in a kidnap gone wrong. It devastated Sandra’s family, but it made her who she is today, one of the FBI’s most successful negotiators. After dropping her teenage daughter, Olivia, at school, Sandra is alerted to a potential hostage situation at her local grocery store and races to the scene. A man has pulled out a gun and is refusing to talk or let anyone out of the building until his demands are met. The fate of dozens of lives rests in Sandra’s hands. But as Sandra starts to make a breakthrough with the hostage taker, she receives a call that makes her blood run cold. Someone has taken Olivia, and their demand will push Sandra to her absolute limit. If it’s not met within twenty-four hours, she will never see her daughter again. Sandra knows she should step aside, letting her team take over, but she doesn’t trust anyone else to bring Olivia home alive. Breaking every rule in the book, Sandra is ready to go into her most personal negotiation yet. But how much will she have to sacrifice to save her daughter? A totally gripping new series which will have you turning the pages long into the night. Perfect for fans of Kendra Elliot’s Mercy Kilpatrick series, Mary Stone and Elle Gray.
