My Sister, Goose
Written by Alyssa Satin Capucilli | Illustrated by Hyewon Yum
When it comes to dressing, Miranda knows her little sister Goose (real name, Graciela Rose) is a free spirit. But a bathing suit at school? Chunky heels at the playground? A tutu in the snow? Goose’s flashy first choices often leave Miranda astonished. But she loves her little sister, and her little sister really, really loooves her clothes. What’s a big sister to do?

Miranda knows! She gently makes suggestions: something to cover the suit? Goose tries on different looks until one is just right and they run off hand-in-hand to the school bus. A different pair of shoes, perhaps? “But I love them . . .” Goose says, doing a little tap dance, but she admits she can climb and “run fast” in her fancy sneakers. Another great choice! Miranda tells her.

All this dressing up points to something else Miranda loves about her sister: her “really big imagination.” Like when they play “Bubble Queen” in the bathtub, complete with frothy crowns for both of them. And when Goose crawls, gallops, and dances in her zebra costume even though bedtime gets delayed and delayed and . . . . Still, Miranda imagines that “Goose had wonderful dreams about zebras that night.”
Sometimes, Goose’s outfits are so perfectly amazing the first time that Miranda asks for fashion advice. She knows, of course, that whatever Goose chooses will be extraordinary—just like her little sister!

There’s so much to love about Alyssa Satin Capucilli’s My Sister, Goose. No sibling rivalry, no tears. Just mutual love, support, and appreciation. Even though Goose’s first inclinations sometimes leave her big sister flabbergasted, Miranda patiently guides her to find her own more practical outfits. Miranda also applauds Goose’s sense of adventure and imagination. While practicality is often appropriate, one of Capucilli’s greatest gifts in this book is Miranda’s openness to embracing her sister’s quirkiness and joining in her free-wheeling, creative, self-expression. Through the sisters’ dialogue, Capucilli also models positive language that encourages instead of discouraging individuality in younger siblings. Capucilli’s direct address to the reader also emphasizes Miranda’s pride in her little sister.
Hyewon Yum’s charming colored pencil illustrations accentuate the loving relationship between Miranda and Goose with plenty of shared smiles, hand-holding, and hugs at home and away. Miranda’s initial reactions to Goose’s outfits are realistic and humorous, making her patience and thoughtful help all the more authentic. Kids will eagerly anticipate each of Goose’s outfits, which are all adorable and as colorful as she is.
Full of humor and heart, My Sister, Goose is a joyful portrayal of sisterly love that both adults and kids will adore sharing again and again.
