Why am I passionate about this?

I’m the author/illustrator of over 20 books for children, ranging from whimsical fiction about anthropomorphic cats and rambunctious dogs to serious nonfiction about hidden children, unusual heroes and surprising spies of WWII and the Holocaust. Several of my nonfiction books, including The Grand Mosque of Paris, were created in collaboration.

The books I picked & why

Book cover of The Harmonica

Karen Gray Ruelle Why did I love this book?

This picture book was inspired by a true story about Henryk, a Jewish boy in WWII Poland. Henryk’s family loved music and enjoyed singing together. They couldn’t afford a piano, so Henryk learned to play Schubert on the harmonica his father had given him. When his parents were arrested by the Nazis, Henryk was deported to Dyhernfurth concentration camp. A Nazi guard heard him playing the harmonica and ordered the boy to play for him. Henryk didn’t want to play for the guard, but he had no choice. Then he found out that he also had another, more important audience: his fellow inmates could hear him play. His music was a gift for them, providing tremendous comfort during a time of despair. 

The text is poetic and powerful, and the illustrations, done in a dark palette, are haunting and exquisite.

What is this book about?

This powerful story, inspired by the life of a Holocaust survivor, is a testament to the human spirit and the transcendent power of music.

When the Nazis invaded Poland, a family is split apart. The parents are sent to one concentration camp, their son to another. Only his father's gift, a harmonica, keeps the boy's hopes alive and, miraculously, ensures his survival. When an officer discovers his talent, he makes the boy play each night. Through music the boy invokes his parents and brings comfort to the other prisoners, lifting their spirits if only for a moment at time.

Book cover of Bartali's Bicycle: The True Story of Gino Bartali, Italy's Secret Hero

Karen Gray Ruelle Why did I love this book?

Gino Bartali was a world-famous champion cyclist from Italy. But the world only learned many years later that he was also secretly working for the Italian resistance during WWII to help save the lives of hundreds of Jewish men, women, and children. He acted as a courier, delivering crucial identity papers and other documents that he had rolled up and hidden in the frame of his bike. Everybody recognized the champion and cheered him on as he raced by. They assumed he was in training. They had no idea that he was using his skills to help battle the enemy and save lives. 

This picture book pops with jaunty graphics and eye-catching illustrations that have a retro feel. The story is exciting and rich with detail.

And powerful leaders declared that Jewish people should be…


Book cover of Nicky & Vera: A Quiet Hero of the Holocaust and the Children He Rescued

Karen Gray Ruelle Why did I love this book?

In 1938, a young Englishman named Nicholas Winton canceled his ski vacation. Instead, he went to Prague to help the Jewish children seeking refuge there from the Nazis. Up until the start of the war in 1939, he made arrangements to send nearly 700 children to safety in England. He did everything from raising funds and locating foster families, to obtaining travel documents—even forging them when necessary. Then he went home and never told anyone what he had done. Fifty years later, his wife found all the records he’d kept and she tracked down as many of those children as she could. A now-famous video clip from a British TV show, “That’s Life,” shows an elderly and very surprised Nicholas as dozens of those he saved stand up in the audience to thank him. Among them was Vera Diamontova, who was just eleven years old when Nicholas saved her life.

This stunning picture book merges the stories of Vera and Nicholas in Peter Sis’s dream-like illustrations and evocative text. It’s a book to savor over and over.

What is this book about?

In 1938, twenty-nine-year-old Nicholas Winton saved the lives of almost 700 children trapped in Nazi-occupied Czechoslovakia-a story he never told and that remained unknown until an unforgettable TV appearance in the 1980s reunited him with some of the children he saved.

Czech-American artist, MacArthur Fellow and Andersen Award winner Peter Sis dramatises Winton's story in this distinctive and deeply personal picture book. He intertwines Nicky's efforts with the story of one of the children he saved-a young girl named Vera, whose family enlisted Nicky's aid when the Germans occupied their country. As the war passes and Vera grows up, she…

Book cover of Odette's Secrets

Karen Gray Ruelle Why did I love this book?

Odette Meyers was a young Jewish girl living in Paris when the Nazis invaded. Her father joined the army and her mother joined the French resistance, so Odette was sent to live with a Catholic family in the countryside, where she would be safe. She had to pretend to be Catholic and keep her secrets locked away. After the war, Odette returned to her family and had to find a way to rediscover her true identity. Writing poetry helped her to adjust and she grew up to be a poet. Macdonald retells Odette’s story in evocative free verse, capturing the poetic voice of a young girl learning how to express her innermost thoughts and feelings during a tumultuous and dangerous time. The reader comes to love this little girl and admire her courage.

Book cover of The Grand Mosque of Paris: A Story of How Muslims Rescued Jews During the Holocaust

What is my book about?

This is a true story that nobody knows about, the hidden history of how the Muslim community of the Grand Mosque of Paris helped to save the lives of Jews and others fleeing from the Nazis. It includes spies and disguises, secret underground passages, and action in the face of grave danger. When my co-author and I discovered this inspiring story of compassion and courage, we knew it needed to be told, so we embarked on years of research to find the truth. And as illustrators, we were inspired by the visual splendor of the mosque, with its colorful mosaic patterns, intricate woodwork, and graceful architecture. It was a joy to paint the illustrations and an honor to unearth this important story and share it with the world.

Rona Simmons Author Of No Average Day: The 24 Hours of October 24, 1944

New book alert!

Why am I passionate about this?

I come by my interest in history and the years before, during, and after the Second World War honestly. For one thing, both my father and my father-in-law served as pilots in the war, my father a P-38 pilot in North Africa and my father-in-law a B-17 bomber pilot in England. Their histories connect me with a period I think we can still almost reach with our fingertips and one that has had a momentous impact on our lives today. I have taken that interest and passion to discover and write true life stories of the war—focusing on the untold and unheard stories often of the “Average Joe.”

Rona's book list on World War II featuring the average Joe

What is my book about?

October 24, 1944, is not a day of national remembrance. Yet, more Americans serving in World War II perished on that day than on any other single day of the war.

The narrative of No Average Day proceeds hour by hour and incident by incident while focusing its attention on ordinary individuals—clerks, radio operators, cooks, sailors, machinist mates, riflemen, and pilots and their air crews. All were men who chose to serve their country and soon found themselves in a terrifying and otherworldly place.
