Mayberry and Garrett Books in Order

The Mayberry and Garrett books shift from the Brooke Grant setup to a two-person team. Valerie Mayberry, a former FBI agent, and Brett Garrett, a former Navy SEAL and security operative, do not bring the same style or instincts to a crisis, and that contrast is a big part of the series' appeal. One leans toward investigation and cover stories, the other toward protection, force, and field judgment.

Collusion throws them into a very current kind of geopolitical thriller. A terrorist strike in Kyiv leaves the American ambassador dying, a sensitive message hidden on a USB drive, and the possibility that a Russian insider wants out. Garrett handles the immediate security side of the crisis, while Mayberry goes undercover to get close to people who may know more than they admit. The result is part spy story, part Washington power game.

Shakedown starts with a murder much closer to home. When an Iranian scientist living near Garrett is killed, the case opens into a web of revenge, covert networks, billionaires, and the threat of something far larger than a single assassination. The series likes that kind of escalation. What looks contained at first rarely stays that way for long.

The setting moves easily between Washington, foreign capitals, intelligence back channels, and private spaces where official power gets bent or sold. That gives the books a slightly different feel from the Brooke Grant novels. They are still fast and political, but more dependent on uneasy partnership, undercover work, and off-the-books problem solving.

Trust is always thin.

If you like thrillers where the central pair has to read people as carefully as they read intelligence reports, this series is an easy fit. Mayberry and Garrett are not polished super-spies. They are competent, pressured, and often working with incomplete information. That keeps the stories moving, and it also gives them a nice edge of unpredictability.
