A romantic suspense novel in Suzanne Brockmann's bestselling Troubleshooters series, blending special-ops action with intense romance. FBI agent Alyssa Locke and Navy SEAL Sam Starrett, whose volatile attraction has simmered across earlier books, are thrown together when Sam becomes the prime suspect in the murder of his estranged wife and the disappearance of a child he never knew was his. As the investigation closes in, the pair must set aside their tangled history to track a killer and protect the boy. Running alongside the present-day manhunt is a parallel storyline set during World War II, exploring racism, courage, and love in a segregated America. The dual narrative deepens the book's themes of prejudice and prejudice overcome, while delivering the high-stakes tension, military detail, and emotional payoff Brockmann's readers expect. Fast-moving and character-driven, it advances the central Sam-and-Alyssa relationship toward a long-awaited turning point while functioning as a propulsive standalone thriller.
