About The Lion’s Run

The acclaimed, New York Times bestselling author of Pax delivers an historical novel about an orphan during WWII who discovers unexpected courage within himself when he becomes involved with the Resistance.

Petit éclair. That’s what the other boys at the orphanage call Lucas DuBois. Lucas is tired of his cowardly reputation, just as he’s tired of the war and the Nazi occupation of his French village. He longs to show how brave he can be.

He gets the chance when he saves a litter of kittens from cruel boys and brings them to an abandoned stable to care for them. There he comes upon a stranger who is none too happy to see him: Alice, the daughter of a horse trainer, who is hiding her filly from German soldiers.

Soon Lucas begins to realize they are not the only ones in the village with secrets. The housekeeper at the German maternity home and a priest at the orphanage pass coded messages; a young mother at the home makes dangerous plans to keep her baby from forced adoption; and a neighbor in town may be harboring a Jewish family.

Emboldened by the unlikely heroes all around him, Lucas is forced to decide how much he is willing to risk to make the most courageous rescue of all.

Perfect for fans of Alan Gratz, Ruta Sepetys, and Kimberly Brubaker Bradley, this accessible novel, told in short chapters, illuminates a little-known aspect of World War II history.

My Review

I could not put this book down. The author’s note at the beginning explains how Sarah Pennypacker learned about the Lebensborn program and the germination process of the idea that became The Lion’s Run.

The Lebensborn program is a part of history that I wasn’t familiar with. This was a Nazi program through which they planned to create a new generation of blond-haired, blue-eyed Germans. They did this by rounding up teenage girls who were pregnant by Nazi soldiers, imprisoning them in these Lebensborn facilities, where they were well-fed and cared for until the birth of their babies, when they were returned home. The babies were then forced into adoption.

Information about the program is pretty limited to keep the story appropriate for a middle grade audience. Lucas meets one of the moms and her baby and sympathizes with her over her situation. It’s also obvious that the girls living at the Lebensborn are well fed when everyone else in Lucas’s town is not getting enough to eat.

In terms of the story itself, I was wholly engrossed. Lucas wants to be brave and worries he isn’t. Yet, he saves kittens from drowning. He hides them, saving food from his own meager meals to give to the little furry critters. He also insists on helping adults in his life who are in the Resistance.

I loved how the story showed him processing the question of what it means to be brave and to help. What a timely message. This will resonate with both middle grade readers and older readers.

I highly recommend this book. It’s a great pick for readers interested in historical fiction, especially those who enjoy stories set during World War II. I think it’ll appeal to readers who like fast-paced stories, too.
