Nighthawk Security Books in Order

The Nighthawk Security books follow the Byrd brothers, five men with backgrounds in military and law enforcement who bring their skills together to run a protection and investigation agency. The setup is simple and effective. Someone is in danger, the regular system is not enough, and Nighthawk steps in.

That family-team energy carries the whole series.

Each book focuses on a different case and usually a different brother, but the series stays tightly connected because the agency itself matters. These men know how to assess risk, plan protection, and track threats, but they also know one another's habits and limits. That gives the books a strong sense of continuity even when the cases shift from stalkers to family secrets to children in danger to suspicious deaths.

The romantic suspense angle is front and center, but Sleeman makes sure the investigations have weight. A governor's daughter is stalked. A woman on the run must protect her child. An FBI agent chases her father's killer. A scientist believes her mother's death was staged. The cases feel personal, which makes the protection work more intense and the emotional payoff stronger.

There is also a nice mix of public and private stakes. Some threats could spill wider, but the books stay anchored in the immediate problem of keeping one person or family alive long enough to uncover the truth. That focus keeps the series fast and readable.

If you enjoy private security teams, former military brothers, and danger that pushes old feelings to the surface, Nighthawk Security is a strong series to read straight through. Start with Night Fall and follow the Byrd brothers from there.
