Mr. Churchill's secretary

"London, 1940, and Maggie Hope has graduated at the top of her college class, but her gender qualifies her only to be the newest typist at No. 10 Downing Street. Her indefatigable spirit and remarkable gifts for code breaking, though, rival those of even the highest men in government, and Maggie finds that working for the prime minister affords her a level of clearance she could never have imagined. Access to the War Rooms also exposes Maggie to the machinations of a menacing faction determined to do whatever it takes to change the course of history."--Publisher description.
