The Winter Soldier (novel)

The Winter Soldier is a 2018 historical novel written by Daniel Mason. Set in 1914 Vienna, it tells the story of Lucius, a 22-year-old medical student, and a field hospital nurse following the outbreak of World War I. The novel focuses on themes including war, historical medical practices, family, and the role of chance in the formation of relationships, history and penance. It also describes the origins and early treatment of what Mason describes as "a new disease, born of the war", post traumatic stress disorder.

Since the book's release Mason has stated that the book's title refers to both the character of Horvath and the main character Lucius, remarking “Even though the diagnostic mystery is Horvath, my interest is in who Lucius is. The title refers to both of them. But the real winter soldier is the doctor and the real investigation is of his trauma and regret.”
