Emma Carter, a single mother and ER nurse, doesn't know her new neighbor is a hired killer. Adrian Cross moved next door with one job: kill Emma in 72 hours. But he never expected her eight-year-old son Leo—a quiet boy carrying a broken robot from his dead father. When Leo wanders into Adrian's house and calls him "Dad," the hitman's one rule—never kill in front of a child—begins to crack. As Adrian protects Emma from a rival assassin, he discovers her husband Daniel, supposedly dead for three years, is alive and behind the contract. Daniel wants Emma dead to seize a 300-million-dollar trust that would pass to Leo. Now Adrian must choose: complete the job, or become the father Leo never had. With federal agents closing in and a second hitman on their trail, Emma and Adrian are forced into a dangerous alliance—one that blurs the line between protector and predator. In a world where every shadow hides a gun, the only thing more lethal than a killer is a mother protecting her son.
