The Secret Messenger
From the description: The world is at war, and Stella Jilani is leading a double life. By day she works in the lion’s den as a typist for the Reich in Venice; by night, she risks her life as a messenger for the Italian resistance. Against all odds, Stella must impart Nazi secrets, smuggle essential supplies and produce an underground newspaper on her beloved typewriter. Set between German-occupied 1940s Venice and modern-day London, this is a fascinating tale of the bravery of everyday women in the darkest corners of WWII.
