The librarian spy / Martin, Madeline

"Posing as a librarian in Lisbon while working undercover as a spy gathering intelligence during WWII, Ava . . . connects with a woman who runs a printing press in occupied France through coded messages that bring hope in the face of war"--Provided by publisher.

World War II in Europe rages as librarian spies Ava and Elaine continue working for the Allies: the U.S. military brings Ava to Lisbon to pose as a librarian, but really to gather intelligence for them, while Elaine starts working for the Resistance in occupied France running a printing press the Nazis desperately want to shut down.
