The game of espionage catches up to everyone in the end. Now, in Greg Rucka’s sensational new Queen & Country thriller, the world’s most lethal woman embarks on one final and all-too-likely fatal mission.

For nearly a decade Tara Chace has been Britain’s top covert agent. But Chace is past her expiration date. Her body hurts. Her nerves are scrambled. She’s ready for a desk job, the quiet role of mentor to a new generation of special operations officers. But before her replacement can be chosen, there’s one last job for Queen and country . . . and it may be the last thing she does. Ever.

The assignment begins with an enigmatic message from Iran—a message made all the more perplexing not just by its cryptic code but by its apparent dispatcher. But what if the long-dormant cipher is a trap meant to entice Iran’s enemies into the open? There’s only one way to find out—and only one agent who can do it: Tara Chace.

Soon Chace is on the ground in Tehran leading an extraction team toward a high-profile defector. But obtaining him is one thing, getting him out of the country will be another. For with the likelihood of a double cross at every turn, Chace knows that chaos can erupt in a heartbeat. And when it does, it’s far worse than even she expects.

Now, if she’s to have a future, Chace must survive any way she can. And that means one thing hasn’t changed: Tara Chace is never the hunted. She’s always the hunter.
