Last Stand (Emma Last FBI Mystery #15)

The line between love and vengeance was never thin. It was a fuse.

After a deadly shootout between impostor agents and the FBI’s Violent Crimes Unit, Special Agent Emma Last thought nothing could shock her again. But when her friend is found hacked to pieces, her severed hand left on Emma’s doorstep like a calling card, the violence veers into something darker—intimate, targeted, and cruel.

And the horror is just beginning.

An FBI bomb specialist is next—his mutilated body scattered like shrapnel in his own home. Emma suspects her long-lost sister may be behind the attacks, but the truth is tangled in blood, betrayal, and lies. Whoever the killer is, she’s escalating. Armed with a weapon that defies science and fueled by a personal vendetta, her target isn’t just Emma.

It’s everything—and everyone—Emma loves.

With guilt mounting and chaos closing in, Emma must outmaneuver a killer who’s always one step ahead. Before the next ignition. Before her team suffocates. Before everything—and everyone—is consumed.

Last Stand, the explosive fifteenth and final installment in the Emma Last FBI series by bestselling author Mary Stone, delivers a heart-stopping finale full of devastating twists, hard-won healing, and one unforgettable goodbye. A story that proves family can break you…or save you. And sometimes, it’s hard to tell which is which.
