In the summer of 1941, German troops laid siege to the city of Leningrad (present-day St. Petersburg). The siege lasted nine hundred days and was one of the most tragic periods in the history of the city. While escaping across Lake Ladoga, Nicolae, a fifteen-year-old Russian boy, reluctantly agrees to take a Jewish orphan girl named Esther with him. The two set off together to find refuge in a city in Finland where they can only guess they will be safe. Along the way, Nicolae encounters secrets and betrayals that will ultimately change his life and discovers just how important protecting a nine-year-old girl can be.

Soon, she's sent to the prairies to fight a whole new war against the 'savage Indians'. Trapped in a world of injustice and inequality, it's only when Charley is posted to Apache territory that she begins to learn what it is to be truly free.

The epic story of war and medicine from the award-winning author of North Woods and The Piano Tuner is "a dream of a novel...part mystery, part war story, part romance" (Anthony Doerr, author of All the Light We Cannot See). Vienna, 1914. Lucius is a twenty-two-year-old medical student when World War I explodes across Europe. Enraptured by romantic tales of battlefield surgery, he enlists, expecting a position at a well-organized field hospital. But when he arrives, at a commandeered church tucked away high in a remote valley of the Carpathian Mountains, he finds a freezing outpost ravaged by typhus. The other doctors have fled, and only a single, mysterious nurse named Sister Margarete remains. But Lucius has never lifted a surgeon's scalpel. And as the war rages across the winter landscape, he finds himself falling in love with the woman from whom he must learn a brutal, makeshift medicine. Then one day, an unconscious soldier is brought in from the snow, his uniform stuffed with strange drawings. He seems beyond rescue, until Lucius makes a fateful decision that will change the lives of doctor, patient, and nurse forever. From the gilded ballrooms of Imperial Vienna to the frozen forests of the Eastern Front; from hardscrabble operating rooms to battlefields thundering with Cossack cavalry, The Winter Soldier is the story of war and medicine, of family, of finding love in the sweeping tides of history, and finally, of the mistakes we make, and the precious opportunities to atone. "The Winter Soldier brims with improbable narrative pleasures...These pages crackle with excitement... A spectacular success." —Anthony Marra, New York Times Book Review
