Someone set the board. Someone else lit the fuse.

Ever since FBI Special Agent Olympia Smith learned her parents died in a house fire, flames have felt personal. So when she witnesses an explosion tear through a high-rise, she doesn’t hesitate. She runs straight toward it. Inside, a federal judge lies dead. Evidence of a carefully planted bomb points to one conclusion.

This isn’t just murder. It’s a message.

The judge made a career putting powerful criminals behind bars. Plenty of enemies. But hours before the explosion, his stepson posted a video claiming the judge was part of a secret network of high-ranking officials operating above the law.

It sounds unhinged.

Until another name from the video turns up dead in a second explosion.

Now Olympia is chasing a killer with the resources to strike again—and the reach to hit closer than she ever expected. Ties to her partner’s father. Questions inside the FBI. And secrets from her own past she’s only just starting to uncover.

This isn’t just revenge. It’s a game of vengeance. And Olympia just stepped onto the board.

The Vengeance Game is the third book in the thrilling new Olympia Smith FBI series by bestselling authors Mary Stone and Matt Giegerich, where a deadly conspiracy turns revenge into a game—and the truth is the deadliest weapon of all.
