Artemis Procter returns in David McCloskey's electrifying new spy thriller, where London has devolved into a covert battleground between British and American intelligence services.

A new US administration has taken office, installing a brash and unconventional CIA director skeptical of old alliances and determined to disrupt the Agency. When the axe falls on the chief of London Station, the agency veteran decides to spy for the Brits?a betrayal uncovered by his replacement, Artemis Aphrodite Procter. Caught between a turncoat spymaster and a ruthless new boss back at Langley, Procter must now navigate a tense environment as old friends become adversaries and no one knows whom to trust.

Adding to the chaos is a new breed of private intelligence agency: a secretive and powerful company run by a reclusive billionaire with a very different agenda than the two old allies who are suddenly at each other's throats.

When assets begin dying, Procter and her team in London Station must find out who is leaking the sources' identities?and why?before both agencies go blind. Soon they will have to decide whether loyalty to the Mission means disobeying the Agency they serve. Immersing readers in the technological revolution upending intelligence tradecraft, London Station explores the changing nature of the spy business and what happens when politics threaten to destroy the special relationship between America and Britain.
