The Lost Sister of Fifth Avenue: Completely unforgettable and heartbreaking World War 2 historical fiction

New York, 1938: Martha pulled the door of her Fifth Avenue apartment closed, her heart thumping, re-reading the telegram she'd been dreading. Her beloved sister Charlotte needed her help. She was alone in Paris, and the threat of Nazi invasion was growing ever stronger. The time had come for Martha to make the bravest decision of her life. She needed to bring Charlotte home. As Martha looks out of her bedroom window at the blossom-covered trees in Central Park, she is a world away from Europe and the threat of war. But when a telegram arrives from her sister Charlotte telling of the death of their Jewish friend Anita, Martha's quiet life changes in an instant. With the threat of the Nazi invasion growing, Martha knows she must travel to Paris to convince Charlotte to return home. When Martha arrives, she finds a city preparing for war. Soldiers patrol Paris' cobbled streets and families talk of packing up and fleeing with whatever they can carry. Clutching her sister tightly, Martha knows that Charlotte has already decided to stay. Charlotte's heart is in France, and as an American in Paris she believes she will be safe. When the Nazis march through Paris' streets and raise their flags over the city's most beautiful buildings, Charlotte is determined not to give in. She works for the Resistance with a Frenchman named Louis, carrying messages, and hiding Anita's family's precious art collection from the Nazis. Meanwhile, Martha vows to help a female Jewish professor to safety in America, only to be faced with impossible odds.
