About the book:
From the New York Times bestselling author of The Last Bookshop in London comes a moving new novel inspired by the true history of America’s library spies of World War II.

Ava thought her job as a librarian at the Library of Congress would mean a quiet, routine existence. But an unexpected offer from the US military has brought her to Lisbon with a new mission: posing as a librarian while working undercover as a spy gathering intelligence. Meanwhile, in occupied France, Elaine has begun an apprenticeship at a printing press run by members of the Resistance. It’s a job usually reserved for men, but in the war, those rules have been forgotten. Yet she knows that the Nazis are searching for the press and its printer in order to silence them. As the battle in Europe rages, Ava and Elaine find themselves connecting through coded messages and discovering hope in the face of war.

About the author:
Madeline Martin is a New York Times and International Bestselling author of historical fiction and historical romance. She lives in sunny Florida with her two daughters (known collectively as the minions), one incredibly spoiled cat, and a man so wonderful he's been dubbed Mr. Awesome. She is a die-hard history lover who will happily lose herself in research any day. When she's not writing, researching or 'moming', you can find her spending time with her family at Disney or sneaking a couple spoonfuls of Nutella while laughing over cat videos. She also loves research and travel, attributing her fascination with history to having spent most of her childhood as an Army brat in Germany.
