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.
The Bulletin of the Center for Children's Books
Claudia has a “sticky” little sister, Monica, who is attached to Claudia like a wad of bright pink bubblegum. This is fine when they play together, but Claudia begins to feel a frustration that builds into gritted teeth anger at her sister’s constant presence. Her breaking point comes when their mother calls Claudia’s soccer coach to ask if Monica can attend her tournament as the “cheerleader.” Determined to stop her, Claudia begins brainstorming various plans to get Monica to back out, but begging wouldn’t work (“Monica is better at that”), and crying won’t work since her sister “cries louder and longer.” Finally, after a misguided attempt at scaring Monica out of coming, Claudia confesses that she wants to go to her tournament with just her friends, and Monica surprisingly agrees, instead electing to go to the beach with their cousins. The sisters make up by blowing bubblegum balloons so large they pop and get enmeshed in both girls’ hair. As the two brown-skinned, brown-haired siblings move through their days, their exaggerated expressions telegraph joy, despair, and frustration to great comedic effect while the bubble gum motif appears throughout scenes dominated by a cheery palette of pinks in all shades. In an author’s note, Siquiera describes her Brazilian heritage and being part of a multicultural Cuban and Brazilian family, which may explain some more regionally distinct terms that are slightly different from Cuban Spanish (figuritas meaning trading cards instead of action figures, pis meaning pee). Both versions are easy, humorous reads, perfect for kids having a difficult time separating from their family, and the story ends on a loving final image: sisters finally separated in their own locations but still looking toward each other with love—and with matching shaved spots on their heads.
Booklist
Claudia and Monica love being sisters. They do everything together, from playing to making Brazilian pastries. But sometimes together can be too much. Little sister Monica doesn’t want to miss out on anything Claudia is doing, and her intrusive habits are feeling . . . sticky: “Following-Claudia-and-amigos-around sticky. Always-invading-games sticky.” Finally, Claudia gets the courage to tell Monica that she would like to go to her soccer game alone, but that she’ll play with Monica afterward. And, to her surprise, Monica is OK with that because she decides that she’ll go to the beach with her cousins instead. This is a great read-aloud about sibling love, conflict resolution, communication, and compromise. The boldly colored illustrations by De Castro are eye-catching and expressive as they depict the big feelings the sisters are experiencing. An author’s note explains how this story is based on Siqueira’s relationship with her own little sister as they grew up in Brazil. A helpful glossary of the Spanish words concludes. Also available in a Spanish edition, Hermana pegajosa.
School Library Journal
A sticky-sweet story about two sisters who love each other but sometimes need some space, from the author of If Your Babysitter Is a Bruja. Older sister Claudia has grown tired of her sister Monica tagging along with every activity she does. Monica has become a sticky sister, and Claudia is desperate to become unstuck. When an opportunity comes up for Claudia to attend a sports tournament, she thinks this might finally be her moment to be alone. But alas, no luck. Claudia tries to escape her situation by concocting various ways to stop Monica from coming along. After a mysterious mention of a bubble gum monster and lots of tears, Claudia finally is honest with her sister about what she feels, and it works—she is finally unstuck. With a smattering of Spanish, Siqueira builds a world influenced by Cuban and Brazilian culture, reminiscent of her own relationship with a sticky sister. The illustrations are boldly crafted and brightly colored in childlike cartoon style; the sisters have brown skin in slightly different hues and brown hair.VERDICT This title is one any pair of sisters can relate to and encourages being honest with familial frustrations. A recommended general purchase for picture book collections.
