Last Shield (Emma Last FBI Mystery #14)

The past has a pulse. And it’s hunting her.

FBI Special Agent Emma Last is still trying to catch her breath after what went down in Salem. The trauma lingers. The secrets she’s held tight? Not so secret anymore. And as her team reels from the fallout, her once-solid foundation is starting to crack.

And that’s not even the worst of it.

When a rookie DC cop is gunned down in a federal garage by someone wearing an FBI windbreaker, the storm only intensifies. The killer might be posing as one of their own—or worse, might actually be one of them. Before Emma can make sense of the ambush, another officer’s gunned down.

Now it’s not just murder—it’s a message.

The media is circling. Tensions are high. And the arrival of a new agent with a murky past is the last thing she needs.

As questions mount and alliances shift, Emma must navigate a minefield of suspicion, betrayal, and a personal vendetta that may trace back to a sister she’s never met. One with a dangerous grudge—and a growing body count.

Last Shield, the gripping fourteenth book in the Emma Last FBI series by bestselling author Mary Stone, is a razor-sharp psychological thriller where trust can be weaponized—and the enemy might already be inside the circle.>
