The untold story of Jewish women resistance fighters battling Nazi occupation, "The Light of Days" reveals history's forgotten heroines. Optioned by Steven Spielberg himself, this New York Times bestseller asks: what drives ordinary women to become extraordinary warriors in humanity's darkest hour?
Judy Batalion is the New York Times bestselling author of The Light of Days: The Untold Story of Women Resistance Fighters in Hitler’s Ghettos, a groundbreaking work of historical nonfiction that reclaims the narratives of Jewish women who orchestrated resistance efforts during the Holocaust. Born in Montreal and fluent in Yiddish and Hebrew, Batalion holds a BA in the History of Science from Harvard and a PhD in Art History from the University of London.
Her academic background and multilingual skills fueled her decade-long research into forgotten archives, including a 1946 Yiddish text that inspired the book’s revelatory accounts of courage, sabotage, and feminism in Nazi-occupied Poland.
Batalion’s prior memoir, White Walls: A Memoir About Motherhood, Daughterhood, and the Mess in Between, explores intergenerational trauma and identity—themes that resonate in her historical writing. A frequent contributor to the New York Times, Vogue, and the Washington Post, she blends rigorous scholarship with accessible storytelling.
The Light of Days has been translated into 19 languages, adapted into a young readers’ edition, and optioned by Steven Spielberg’s Amblin Partners for a major film. It won the National Jewish Book Award and the Canadian Jewish Literary Award, solidifying Batalion’s reputation as a vital voice in Holocaust historiography.
The Light of Days unveils the heroic, untold stories of Jewish women resistance fighters in Nazi-occupied Poland during WWII. These women smuggled weapons, bombed train lines, gathered intelligence, and even seduced Gestapo officers to sabotage Nazi operations. Centered on figures like Renia Kukielka, the book blends harrowing survival narratives with tales of female camaraderie and defiance, reclaiming a vital chapter of Holocaust history.
This book is essential for readers of WWII history, Holocaust studies, or feminist narratives. It appeals to those seeking stories of underrecognized heroism, as well as fans of works like Hidden Figures or Band of Brothers. Historians and educators will value its meticulous research and firsthand accounts of resistance.
Yes. Hailed as "resounding" (Kirkus) and "groundbreaking" (The Boston Globe), it offers a gripping, meticulously researched account of courage amid genocide. The narrative’s blend of personal diaries, interviews, and historical analysis makes it both a scholarly resource and a page-turning tribute to unsung heroines.
Renia Kukielka, a weapons smuggler and escape artist, is central, alongside other couriers, fighters, and saboteurs like Chajka Klinger and Zivia Lubetkin. These women used their Aryan-looking features, wit, and resilience to orchestrate escapes, smuggle documents, and execute covert attacks across Polish ghettos.
Batalion drew from Yiddish texts like Freuen in di Ghettos, survivor testimonies, and archival materials. Her grandfather’s Holocaust survival story motivated her to explore these narratives, culminating in over a decade of research across libraries, interviews, and Holocaust memorial sites.
Couriers disguised as non-Jewish Poles transported weapons, forged papers, and intel across ghettos. They bribed guards, hid revolvers in food jars, and coordinated with underground networks—roles deemed too dangerous for men, who faced higher deportation risks.
Unlike many Holocaust accounts focused on victimhood, this book highlights proactive resistance. It parallels Hidden Figures in reclaiming women’s contributions but stands out for its visceral, unflinching portrayal of sabotage and survival in occupied Poland.
Key themes include female empowerment, moral courage, and the cost of resistance. It also examines how trauma and friendship sustained these women, offering a nuanced look at ethics in extremis, such as using seduction or deceit to save lives.
Some critics note its dense cast of characters and nonlinear structure can challenge readers. However, most praise its rigor and emotional impact, with The Wall Street Journal calling it a "well-researched and riveting chronicle".
Yes. Twenty black-and-white photographs document the women, their missions, and postwar lives, adding visceral depth to their stories.
It reframes historical narratives to center women’s agency, resonating with modern conversations about gender and resilience. Its lessons on moral courage and collective action inspire contemporary social justice movements.
By weaving personal diaries, survivor interviews, and historical context, Batalion elevates their legacies beyond footnotes. The book serves as both memorial and manifesto, ensuring their defiance and ingenuity are remembered.

A faded Yiddish book sits in the British Library, its pages yellowed with secrets. Inside, stories pulse with a truth so startling it rewrites everything we thought we knew about the Holocaust. Young Jewish women-teenagers, really-smuggling dynamite in potato sacks, firing pistols with both hands, commanding partisan units through frozen forests. These weren't victims waiting for rescue. They were architects of resistance, and history nearly forgot them entirely. We've seen the films, read the textbooks. The Holocaust narrative typically centers on suffering and survival, with rescue coming from outside. But what if I told you that over 90 ghettos mounted armed resistance? That 30,000 Jews fought as forest partisants? That women formed the backbone of these networks, yet their stories vanished from collective memory? This erasure wasn't accidental-it was systematic, shaped by Cold War politics, gender bias, and the discomfort of imagining victims as warriors. Picture Jedrzejow, Poland, 1938. Nearly half the town is Jewish. Renia Kukielka, fourteen, dreams of office work, practicing stenography while her older sister Sarah attends meetings of Freedom, a Labor Zionist youth movement. These weren't just social clubs-they were training grounds for revolution, teaching agricultural skills, self-defense, and radical ideas about gender equality that would seem progressive even today. These movements gave young Jews something precious: purpose in a world turning hostile.
