Some memories detonate on impact.

Fresh from the adrenaline rush of her latest case, FBI Special Agent Emma Last dropped a bombshell on her friend and coworker Mia Logan—she can communicate with ghosts. Worse, one spectral figure is Mia’s brother.

And he insists he was murdered.

But there's little time to grapple with the supernatural when the Violent Crimes team is thrust into the heart of Randall County, West Virginia where a local diner is reduced to rubble in a powerful explosion. Although the owner and his daughter live above the restaurant, no human remains are found in the rubble. Did they have the motive, or the skill, to make a bomb?

Or are they the victims of a more disturbing vendetta?

The stakes heighten when another local diner faces the same fate, its owner and his daughter also conspicuously missing. The pattern is undeniable. As a winter storm encroaches, Emma and her team are in a race against time to find the victims before a third explosion blows Randall County apart.

Last Chance, the fourth book in the captivating new FBI series by bestselling author Mary Stone, drives home a haunting reality: you don’t need enemies to become a target.
