A memoir of service by the American ambassador who was on the diplomatic front lines when Putin invaded Ukraine, Midnight in Moscow is the first behind-the-scenes account of how U.S.-Russia relations hit their nadir—and a playbook for our unfolding confrontation.

For weeks before Russia’s invasion of Ukraine, John J. Sullivan, the U.S. ambassador in Moscow, was warning that it would happen. When troops finally crossed the border, he was woken in the middle of the night with a prearranged code. The signal was even more bracing than the February cold: it meant that Sullivan needed to collect his bodyguards and get to the embassy as soon as possible. The war had begun, and the world would never be the same.

In Midnight in Moscow, Sullivan leads readers into the offices of the U.S. embassy and the halls of the Kremlin during this climactic period—among the most dangerous since World War II. He shows how the Putin regime repeatedly lied about its intentions to invade Ukraine in the weeks leading up to the attack, while also devoting huge numbers of personnel and vast resources to undermining the U.S. diplomatic mission in Russia. And he explains how, when Putin ultimately gave the order to launch a full-scale invasion of Ukraine on February 24, 2022, he proved that Russia was not just at war with its neighbor: it was also at war, in a very real sense, with the United States, and with everything that it represents. But while Putin decided how this conflict started, its ending will be shaped by us.

With his unique perspective on a pivotal moment in world history, Sullivan shows how our relationship with Russia has deteriorated, where it’s headed, and how far we should be prepared to go in standing up to the menace in Moscow.
