Dr. Grace Kendal never stands a chance. The injured woman comes out of nowhere, bleeding heavily and holding a gun. Compelled to help her, Grace is dragged into Elin Breckenridge's nightmare. Their fight to survive will take them across the country and to the limits of their endurance. But who is Elin running from? As Grace struggles for answers, one thing becomes clear?Elin is somehow connected to a dead man, and Grace could be next.

For Detective Sergeant Safia Faris, the case should have been easy: one dead body, one suspect. But the deeper she digs, the more obvious it becomes that murder was only the beginning. The investigation sets her on a collision course with Grace and Elin, and she's forced to reevaluate everything she knows. Because nothing is quite as it seems, and Grace's and Elin's lives aren't the only ones on the line.
