In August 1939, in Warsaw, twenty-two-year-old Herschel Skolnik is a watchmaker’s apprentice, a rare Jewish captain in the Polish army, and a man with an unusual skill: pressing two blades of grass between his thumbs and blowing through them to mimic the call of a mistle thrush. When the German invasion shatters Poland’s defenses, Herschel trades his officer’s uniform to march into captivity alongside his enlisted men, beginning a four-year fight for his family and his country.

After escaping his first prisoner-of-war camp, Herschel returns to occupied Warsaw to lead a unit of forest partisans who use his grass-blade birdsongs as battlefield signals to ambush German patrols. In the woods outside the city, he meets Ida, a resistance nurse who fights beside him as the walls of the Warsaw Ghetto close around his family.

From the interrogation cells of a Gestapo prison and a midnight raid on a Treblinka-bound death train to Auschwitz, where a hollow marsh reed in a camp cesspit becomes his only chance at escape, Herschel and Ida risk everything to protect each other, settle a blood debt with the SS officer who murdered his loved ones, and cross the winter Alps toward freedom.

Generative Biographical Illustration

The Shepherd’s Blade draws directly from the real-world survival and partisan resistance of the author’s grandparents in occupied Poland. Throughout the book, pivotal scenes are brought to life through Generative Biographical Illustration (GBI), a visual method developed by the author that anchors dramatized historical illustrations to a surviving period portrait from the era.
