The Secrets We Kept by Lara Prescott is a novel based out of the true story that the CIA during the Cold War worked to make available in Russia the banned book Doctor Zhivago by Boris Pasternak.
Prescott imagines and writes of spies coming out of a CIA secretarial pool, love, and betrayal from Washington to Russia, and her novel has met fairly large acclaim, as noted in this review from The Guardian.
