Having a sister who wants to do everything together is a pain! But in the end, big and little sisters always find a way to make up.

A fun read-aloud picture book with some Spanish words that’s full of humor and heart and perfect for 3-7-year-olds with a younger or older sibling.


Claudia is the big sister. Monica is the little sister. Having each other is fun. They do bubblegum peace bubbles, where they each blow a bubble and almost touch them together.

But sometimes Monica is just way too sticky—wanting to do everything Claudia does. And Claudia finally loses it when Monica tries to come to her soccer tournament. She tells her little sister that there’s a monster that eats little kids. Then, just like siblings do, they work it out and make up.

But when those bubblegum peace bubbles go awry, it brings an entirely new definition to the word sticky!

Back matter includes an author’s note and a Spanish-word glossary. Sticky Hermana releases simultaneously in Spanish as Hermana pegajosa.

Sibling relationships can be tough—even sticky.
Claudia loves her little sister, Monica. After all, it’s fun to always have someone to play with. But sometimes Monica sticks to her like glue, trailing after Claudia and her friends and inserting herself into their games. When Claudia is invited to a fútbol tournament, Monica begs to come along. Claudia knows her sister will be crushed if she’s not included, but she longs for an activity that’s just her own. Claudia considers her options—pleading, bribing, even warning her sister about a scary monster. Nothing works. At last, Claudia turns to the hardest strategy of all: honesty. She explains that she simply wants to play with her friends on her own. To her surprise, Monica understands and agrees not to go. The sisters seal their new understanding by chewing some bubble gum, leading to a hilarious and literally sticky situation. Readers who have weathered both loving and exasperating sibling relationships will see themselves in this heartfelt story. The push and pull between the sisters feels authentic even as Siqueira maintains a playful, humorous tone, matched by de Castro’s exaggerated cartoon artwork. Spanish vocabulary is seamlessly woven throughout, and Claudia’s family members are brown-skinned and cued Latine.
A funny and tender celebration of sisterhood, honesty, and finding space while staying close.
