It’s Memorial Day weekend! For a lot of people, this holiday marks the start of summer—but it’s also a time to honor the men and women who lost their lives while serving in the U.S. military, often while fighting a war. 

Imagine what it was like to be a kid during World War I (1914-1918) or World War II (1939-1945). One of my favorite things about books is the way they can take you to a whole different time and place. Maybe back to when your great-great-great-great-grandparents were your age. Or even before that!

Are you up for a little time travel? This weekend is the perfect time to join people doing brave, adventurous things in a dark and dangerous world. (Between the pages of a book, of course.) You’ll meet some of them in this list of books set during World Wars. Some of them are true stories or based on a true story.

Once you’ve been on an adventure or two, come on over to my Instagram page and share your favorite historical book.

P.S. If you want to travel even farther back in time, check out my post on 20 Middle-Grade Books About the Revolutionary War.

1.  Journey to America by Sonia Levitin

Then their neighbors get arrested and the Platts know they have to escape. Forbidden to bring money or possessions out of the country, Lisa’s father secretly leaves for America, planning to work until he can send for them. But things get so bad that the family can’t wait. Lisa flees with her mother and sisters to Switzerland to try and survive. Based on the author’s real-life experience!

3. The Ghost Garden by Emma Carroll

SUMMER 1914:  Fran uncovers a bone in the garden the same afternoon that Leo breaks his leg. Coincidence? Maybe…but it won’t be the last one that summer. Fran gets roped in to keep Leo company, forced to listen to his foolish theories about the looming threat of war in Europe. Suddenly the garden she has loved all her life seems to hold threatening shadows of the future, and Fran starts to fear what she and Leo might find next … This is a pretty short book, so if you’re looking for a quick read it’s a good option. If you like it, check out Letters from the Lighthouse, another World War II book by the same author.


4. Number the Stars by Lois Lowry

What would you do if your best friend was in danger? What if helping them put you and your family in danger, too? In 1943, as the German troops begin their campaign to “relocate” all the Jews of Denmark, Annemarie Johansen’s family takes in Annemarie’s best friend, Ellen Rosen, and conceals her as part of the family. Through the eyes of ten-year-old Annemarie, we watch as the Danish Resistance smuggles almost the entire Jewish population of Denmark, nearly seven thousand people, across the sea to Sweden. (That really happened!) A Newberry Medal winner.


5. The Watcher by Joan Hiatt Harlow

1942. Just a few months ago, Wendy was in Maine, supporting the American war effort. Then she was kidnapped . . . and discovered that her mother is actually a Nazi spy!

6. The Book Thief by Markus Zusak

I love this book! It is 1939. Nazi Germany. The country is holding its breath. Death has never been busier, and will become busier still. Liesel Meminger is a foster girl living outside of Munich, who scratches out a meager existence for herself by stealing when she encounters something she can’t resist–books.

In it is an old, beautiful Montblanc pen and some letters written in French. Granny tells Lily that the pen is very important and that she has to take care of it. But Lily loses the pen and as she searches for it, she uncovers secrets of her grandmother’s past as a member of the French Resistance during WWII.

16. Pharmacy Girl: The Great War, Spanish Influenza, and the Truth about Billy Detwiler by Kate Szegda

Before COVID there was Spanish influenza. In 1918 there were masks. Schools, restaurants, and even churches closed. One in four Americans stricken, and an estimated 675,000 Americans dead. All because of a deadly germ carried on a puff of air. But there were no effective vaccines. No ventilators. No medicines to stop a virus. And a war to win.

Everyone likes Josie, except the spoiled and arrogant Billy Detwiler. He calls her Pharmacy Girl, but it is no compliment. As the hazy days of September 1918 drift into the deadly autumn of Spanish influenza, Josie’s everyday problems of school and friends, even the war effort at home, become insignificant when her mother comes down with the flu. But Josie is no slacker. She faces Billy in a class election, raises money for the Liberty Loan, and steps up to help her family when the pandemic strikes home. (Amazon description)

18. The Skylarks’ War by Hilary McKay

It’s the early twentieth century, and the only thing girls are expected to do is behave. But Clarry wants to dive off cliffs and go swimming with her brother Peter and cousin Rupert.

19. How I Became a Spy: A Mystery of WWII London by Deborah Hopkinson

Thirteen-year-old Bertie Bradshaw never set out to become a spy. He never imagined traipsing around war-torn London, solving ciphers, practicing surveillance, and searching for a traitor to the Allied forces. He certainly never expected that a strong-willed American girl named Eleanor would play Watson to his Holmes (or Holmes to his Watson, depending on who you ask). But when a young woman goes missing, leaving behind a coded notebook, Bertie is determined to solve the mystery. With the help of Eleanor and his friend David, a Jewish refugee—and, of course, his trusty pup, Little Roo—Bertie must decipher the notebook in time to stop a double agent from spilling the biggest secret of all to the Nazis.
