International Friendship Day is July 30, and we can’t think of a better excuse to share the books on our shelves about friendships that stretch across borders. Some of the most powerful stories in children’s literature start the same way: two people who shouldn’t have anything in common discover that they do. A pen pal letter travels from Pennsylvania to Zimbabwe. The Maasai people of Kenya send a gift across an ocean to a grieving country. Two girls in a Delhi classroom figure out how to be friends even though they can barely understand each other at first.
What we love about these books is that none of them pretend this kind of friendship is effortless. The best ones are honest about the misunderstandings and the awkward starts, and then they show the payoff: a friend who makes your world twice as big. There’s something here for everyone, from simple picture books about sharing to a dual memoir your teenager will finish in two sittings.
Ages 3-5: First Friends, Near and Far
For the youngest readers, friendship across borders starts close to home. A neighbor from another country, a friend in the village, a welcome sign built from stones. These picture books plant the idea early that the world is full of people who are glad to see you.
Madlenka has a loose tooth, and she has to tell everyone. So she goes around her New York City block, where her friends include a French baker, an Indian news vendor, an Italian ice-cream man, a South American grocer, and a Chinese shopkeeper. Peter Sís turns one city block into a trip around the world. Your kid doesn’t need a passport to have friends from everywhere; sometimes a walk around the block will do.
Handa and her best friend Akeyo search for Grandma’s missing black hen, Mondi, and find two fluttery butterflies, three stripy mice, and a whole parade of other animals along the way. Set among Kenya’s Luo people, this is a gentle counting story wrapped around an even gentler friendship story. The warmth between the two girls carries every page. A lovely first look at everyday life in Kenya for little ones.
Mama Panya has just enough money for a few pancakes, but her son Adika keeps inviting every friend they meet on the way to market. We won’t spoil how it resolves. This Kenyan story is one of the best read-alouds we know about generosity, and the endnotes about Kenya and Kiswahili are a nice bonus for curious kids.
Across the Arctic, peoples have long built stone landmarks called inuksuit to point the way, express joy, or simply say: welcome. Mary Wallace builds this picture book around seven Inuktitut words, with rich, textured illustrations. Think about it for a second: a monument whose whole purpose is to greet a traveler you may never meet. That’s friendship across borders in its purest form.
Ages 5-9: Friendship as a Gift
Kids in this range are ready for stories where friendship costs something, where it takes courage or sacrifice. These three are some of the most moving books in our whole collection.
In June 2002, a young Maasai man who had been studying in New York returned home to Kenya and told his village about September 11. The Maasai responded the way their traditions taught them: with cattle, their most precious possession. Fourteen cows, given to a country most of the villagers would never see. This true story gives us chills every single time. If you read one book from this list for Friendship Day, make it this one.
In a South African township, a group of boys play soccer in a dangerous alley with a federation-size ball earned as a school prize. When bullies come to steal it, the boys stick together and outsmart them. Mina Javaherbin’s text reads like a chant, and the message lands hard and true: “when we play together, we are unbeatable.”
Lola was a baby when her family left the Island, so when a school assignment asks her to draw where she’s from, she can’t remember it. Instead, she interviews her family, friends, and neighbors, and their memories become her own. Junot Díaz wrote this picture book about the Dominican diaspora, and we especially recommend it for kids navigating two homes at once.
Ages 8-12: Crossing Oceans and Classrooms
Middle-grade readers can handle friendship’s harder questions. What do you do when your best friend is on the other side of the world? What if your new friend’s life is nothing like yours? These four books answer honestly.
Chloe and Lakshmi are both new to Class Five at Premium Academy in New Delhi. Chloe is an American transplant, Lakshmi a scholarship student, and neither fits in. Kate Darnton is honest about class and privilege in a way few middle-grade novels manage without preaching, and the friendship at the center rings true on every page.
Eleven-year-old Dini is devastated to leave her best friend Maddie in Maryland when her family moves to India for two years, though the chance of meeting her favorite Bollywood star takes the edge off. Uma Krishnaswami’s comedy of coincidences is pure fun. Underneath the Bollywood sparkle is a real story about keeping a friendship alive across ten and a half time zones.
Lincoln Mendoza, a Mexican-American boy from San Francisco, spends a summer in Japan practicing the martial art of kempo. At first he feels like “a brown boy in a white gi.” With the help of Mitsuo, his host brother, he discovers how much they share, from baseball to family expectations. Gary Soto gets the exchange-student experience exactly right, homesickness and small embarrassments included.
Two nine-year-old Jewish boys hide from the Nazis in a forest, surviving on resourcefulness, faith, and each other. Aharon Appelfeld drew on his own wartime childhood for this spare, haunting novel. It’s the most serious book in this section, best for thoughtful readers who are ready for wartime history.
Ages 11 and Up: Letters That Change Lives
For older readers, we’ve saved the books where a cross-border friendship rewrites a life.
In 1997, twelve-year-old Caitlin in Pennsylvania was assigned a pen pal: Martin, a boy in Harare, Zimbabwe. Their letters continued for six years, through Zimbabwe’s economic collapse and Martin’s family’s deepening poverty, and changed both of their lives completely. The real Caitlin and Martin tell the story in alternating chapters. This is the single best book about international friendship we know, and it sparks the kind of dinner-table conversation you hope a book will.
Sunny was born in New York and lives in Nigeria, an albino girl who feels at home nowhere. Then she discovers she’s a “free agent” with latent magical ability and falls in with three friends who train together in the hidden Leopard society. Nnedi Okorafor’s fantasy has been called “the Nigerian Harry Potter,” but what our readers remember is the found family of four kids from wildly different backgrounds who need each other.
