All Hanna Fischer ever wanted to do was to study physics - but her world is suddenly turned upside-down and she is catapulted into a new and extraordinary life: as a secretary, a scientist, a sister and a spy.

From racist gangs in Berlin to mobsters in New York City, and Hitler's inner circle during the Second World War, Hanna encounters some of history's greatest minds and most terrible moments, all while desperately trying to stay alive.

She is a most unique secretary and she will work for many bosses - from shrewd businessmen to vile Nazis, to the greatest boss of them all, Mr Albert Einstein . . .
