Nineteen-year-old Libby moves to Berlin to escape her suffocating family - but instead of offering freedom, the city is under siege by the Nazis. Jewish books are burned, storefronts smashed and every day innocent people vanish into thin air. Libby cannot - will not - turn a blind eye. When Libby meets Harro, she knows there's more to him than his dazzling smile and cornflower-blue eyes. The whip marks on his back, scars from the SS, tell his true story: He is a resistance fighter. Libby and Harro fall madly in love, devoted to each other and to tearing down Hitler's regime. Knowing they can make the greatest difference from the inside, Harro works for the Air Ministry, infiltrating government secrets. Together, they smuggle classified documents and hold clandestine meetings in the middle of the night, with blackout curtains and a single candle burning. Under the cover of darkness, they distribute leaflets, exposing the Nazis' hideous lies. In the frostbitten winter of 1942, Libby is certain the Gestapo is stalking them - their every move watched, their phone calls recorded. In the end, they must decide what is more important: to be free or to be brave? To survive or to stand up for the truth?
