Dr. Eliza Crane's hands have trembled too violently to operate since the day her ex-husband Marcus destroyed her career and her life—so when he arrives at her remote field hospital begging her to save his critically injured wife, she faces an impossible choice. But Marcus doesn't know that Eliza's tremor is his fault, that her parents died in the aftermath of their divorce, or that the woman he's brought to her tent isn't who she claims to be. As Eliza is forced back into surgery for the first time in five years, she discovers Marcus has been tracking her camp for weeks and that a dangerous arms dealer is already on his way to settle a debt she didn't know existed. With less than twenty-four hours before everything collapses, Eliza must decide whether to flee and save herself or stay and operate—knowing that her choice will determine not only who lives and who dies, but who will face twenty years in prison for crimes they may or may not have committed. In a place where loyalty is measured in blood and redemption comes at the cost of sacrifice, the steadiest hands belong to the person with the most to lose.
