In a late-night showdown, Detective Lindsay Boxer has to make an instantaneous decision: in self-defence she fires her weapon and sets off a chain of events that leaves a police force disgraced, a city divided and a family destroyed. Now everything she s worked for her entire life hinges on the decision of twelve jurors.

To escape the media circus, Lindsay retreats to the picturesque town of Half Moon Bay. Soon after, a string of grisly murders punches through the community. There are no witnesses; there is no pattern. But a key detail reminds Lindsay of an unsolved murder she worked on years ago. As summer comes into full swing, Lindsay and her friends in the Women s Murder Club battle for her life on two fronts: in court and against a ruthless killer.
