This is the astonishing story of the ten million books that US intelligence smuggled across the Iron Curtain during the Cold War.

From copies of Orwell to Agatha Christie, the Western effort was to undermine the censorship of the Soviet bloc, offer different visions of thought and culture to the people, and build relationships with real readers in the East.

Historian Charlie English follows the characters of the era, with Bucharest-born George Minden at the narrative's heart. Tasked with masterminding the effort, Minden understood both sides of the story: he was opposed to the intellectual straightjacket created by the communist system, but he also resented the Americans' patronising tone - the people weren't fooled by what their puppet governments were saying, but they did need culture, diversity of thought, entertainment, art, reassurance and solidarity. This is how the perilous mission to bring books as beacons of hope played out, told in riveting detail.
