The Helpers: Historical Fiction About WWII Humanitarian Heroes

Some of the most courageous acts of WW2 came from ordinary people who opened their homes, shared their meager food rations, forged identity papers, or smuggled children to safety. These individuals, from Polish teenagers hiding Jewish families in their attics to Dutch women assisting with the Kindertransport, risked everything to protect the vulnerable.

The books on this list celebrate these unsung heroes whose resistance took the form of radical compassion and humanitarian aid. While most were not part of organized resistance networks running espionage operations, their work was no less dangerous and no less vital. Each story reminds us that even in humanity’s darkest hours, individual acts of courage and kindness can save lives and preserve hope.

Sunflower House book cover

Book Summary

Allina has a good life in her small German village, where she spends her days working at her uncle’s bookshop, making strudel with her aunt, and spending time with friends and her fiancé. But the year is 1939, and she also has one very big secret that puts everything at risk. Her birth mother was Jewish, which makes her a Mischling.

After losing everyone she loves, Allina is forced to work as a nurse at Hochland Home, a state-run baby factory. There, she becomes not only a witness to, but also a participant in, Himmler’s horrific eugenics program.

To survive, Allina must keep her Jewish identity secret. When she meets a high-ranking SS officer with secrets of his own, she must decide how much she can safely share with him. They each take major risks to join forces and save as many children as possible.

Historical Context

A Mischling was a derogatory legal term used in Nazi Germany under the Nuremberg Laws to classify individuals with both “Aryan” (German/European) and “non-Aryan” (primarily Jewish) ancestry, defining them as “mixed-blood” rather than fully “pure.”

Under the Lebensborn Program of Nazi Germany, Women of “pure” blood stayed in Lebensborn homes for the sole purpose of perpetuating the Aryan population, giving birth to thousands of babies who were adopted out to “good” Nazi families.

Skylark book cover

Book Summary

In 1664, Alouette was the 18-year-old daughter of a master dyer at the famed Gobelin Tapestry Works. She dreams of a life bigger than the one she was born into, but instead, her life takes a terrible turn when her dad is wrongfully arrested. Things get worse when she tries to save him, but instead ends up sent to the Salpêtrière asylum, where thousands of women are held captive and cruelly treated. But she’s not the only brave woman there, and she finds some unlikely allies.

Three centuries later, in 1939, a medical student named Kristof is doing his psychiatric residency in Paris. His neighbors are a Jewish family who fled Poland, but now the Nazis are threatening their new home. Kristof is their only hope of survival. Over the next three years, his life looks dramatically different from what he planned when he entered medical school.

Thoughts on This Book

Unlike most popular dual-timeline novels that contrast WWII with a present-day storyline, Skylark takes us back to a less commonly covered period in history. This would be a great fit for clubs that enjoy historical fiction, but are looking for an interesting twist. Plan on discussing how you think the stories are related to each other.

Be aware that the story starts at a slower pace, and it may take you a bit longer than normal to be hooked. However, reviewers say it’s worth the wait, and you will connect with the characters once you get to know them.

One Good Thing book cover

Book Summary

Lili and Esti met at the University of Ferrara and have been best friends ever since. Both women have Jewish ancestry, which deems them an “inferior” race under Mussolini’s Racial Laws. Life goes on for the two women as a war breaks out across borders until Germany invades northern Italy, and they are suddenly living in occupied territory.

Self-confident Esti convinces Lili to flee to a villa in the countryside and help a group of young war orphans. Then they continue on to Florence, where they pose as nuns and falsify documentation for the Underground. But their biggest risk of all comes when Esti is wounded and asks Lili to run away with her young son in order to protect him.

Traveling alone with the boy, Lili does everything she can to keep Theo safe as they make their way through Allied territory, Nazi-occupied villages, and bombed-out cities.

Book Summary

Lilac Girls crosses three continents and follows three women whose lives are on a collision course. 

Caroline is a New York socialite working at the French consulate, Kasia is a Polish teenager and a courier for the underground resistance movement, and Herta is an ambitious young German doctor who finds herself trapped in a male-dominated world of Nazi secrets and power.

The book alternates between the three stories, each providing thought-provoking insights into uniquely difficult situations as the war progressed.

Our Thoughts on This Book

Melissa loved Lilac Girls, although it includes tragic scenes that are tough to read. She was devastated when she learned that this historical fiction was based on the true experiences of the ‘Ravensbrück Rabbits.’

Specifically, you’ll find this to be the story of two people who choose to be helpers, and one who found herself accidentally aligned with evil.

Get your tissues ready; this story is part of history that we shouldn’t ignore.

Auschwitz Lullaby book cover

Book Summary

Helene is about to wake her children for school in 1943 when German police break into her home to take her Romani husband and five children. Because she is German and not Roma, she doesn’t have to go with them, but she bravely volunteers, unwilling to watch her family face their fate without her.

When Doctor Mengele realizes Helene is a trained nurse, he assigns her to run the camp’s nursery. For sixteen months, Helene becomes a helper, doing everything possible to care for the children and bring them some sense of comfort and hope—all while two gas chambers operate just 400 yards away, with thousands of daily victims.

Based on a True Story

Don’t miss the author’s note, which reveals that Helene was a real person and a little-known hero. Her family was among the 20,000+ Romani people imprisoned at Auschwitz—a group rarely mentioned in Holocaust histories today.

Note: Some reviewers suggest reading this in print or on Kindle, as the audiobook narrator doesn’t always match the story’s tone.

For over two years, Stefania risks her life daily to keep her hidden guests safe—all while caring for her little sister, working to pay the rent, and evading the suspicions of her Nazi neighbors.

Historical Context

This young adult novel is based on the true story of Stefania Podgórska, who was named Righteous Among the Nations by Yad Vashem for her heroic actions during the Holocaust.

Don’t miss the author’s note that provides more details about Stefania’s remarkable story and what happened to the people she saved.

Another Book to Consider

Schindler's List book cover

Book Summary

Oskar Schindler is an unlikely hero: a German businessman, Nazi Party member, and war profiteer who arrives in occupied Poland seeking fortune from the chaos of World War II. He establishes an enamelware factory in Kraków, initially employing Jewish workers simply because they’re cheaper labor.

But as Schindler witnesses the brutality of the Nazi regime, particularly the liquidation of the Kraków ghetto and the horrors of the nearby Płaszów concentration camp, something shifts. He begins using his factory as a refuge, manipulating the system to protect his Jewish workers from deportation to death camps. His list of “essential workers” becomes a list of lives saved.

By the war’s end, Schindler had spent his entire fortune on bribes and black-market goods to keep approximately 1,200 Jews alive. Based on extensive interviews with fifty Schindler survivors and meticulous research, Thomas Keneally’s novel tells the true story of how one man’s moral transformation during humanity’s darkest hour saved generations.

About the Author

Thomas Keneally is an Australian novelist and playwright who has won numerous literary awards, including the Booker Prize for Schindler’s List (originally published as Schindler’s Ark in 1982). The book was adapted into Steven Spielberg’s acclaimed 1993 film.
