"A heart-stopping World War II story of three female code breakers at Bletchley Park and the spy they must root out after the war is over. 1940. As England prepares to fight the Nazis, three very different women answer the call to mysterious country estate Bletchley Park, where the best minds in Britain train to break German military codes. Vivacious debutante Osla is the girl who has everything--beauty, wealth, and the dashing Prince Philip of Greece...

The discovery of a mysterious object in the U.S. Capitol building and a subsequent kidnapping lead Harvard symbologist Robert Langdon into a web of mysterious codes, secret locations, and hidden knowledge.

When Robert Langdon wakes up in an Italian hospital with amnesia, he teams up with Sienna Brooks, a doctor he hopes will help him recover his memories. Together, they race across Europe and against the clock to stop a madman from unleashing a global virus that would wipe out half of the world's population.

A battle-weary Marine is assigned to guard - and ultimately befriends - a young Navajo soldier who has been trained to be a code talker. This code, the Navajo code, and the men who knew the code, were to be guarded as they went into action. It was the unspoken duty of the Marine to kill the Navajo soldier before he could be taken prisoner of war by the Japanese. This is the one wartime code that was never broken by the enemy.
