My Big Sister the Secret Ninja

By Author Mollie Nelson – Wompus Stompus Series

In the quiet corners of childhood where imagination rules and adventure awaits at every turn, My Big Sister, the Secret Ninja tells a tale both whimsical and powerful. This story, like many in the Wompus Stompus series, thrives on a rich blend of everyday family life and extraordinary surprises. Written by , a master of capturing childhood wonder, this particular book explores themes of sibling bonding, hidden talents, and quiet courage through a lens that is as playful as it is sincere.

Hero in Disguise

The narrator of the story is a younger sibling, a curious and wide-eyed child who has always admired their big sister from a distance. She’s smart, cool, and can tie her shoes faster than anyone else. But there’s always been something... different. She moves without a sound. She always knows when someone’s sneaking cookies. She can scale the jungle gym like it’s the side of a mountain. It isn’t until a quiet night when the power goes out that the truth is revealed — she’s a ninja. Not just in imagination, but a real, training-after-bedtime, secret-mission-completing ninja.

Sibling Bond and Emotional Depth

The tone of the story is warm and vibrant, with humor woven through moments of awe and sibling admiration. While the younger sibling is surprised by the revelation, they are not afraid. Instead, the discovery brings the two closer. The sister, once mysterious and somewhat distant in the eyes of her younger sibling, becomes a guide, a mentor, and a hero.

Mollie Nelson has a remarkable gift for blending fantasy with emotional authenticity. Each page of My Big Sister, the Secret Ninja is layered with subtle truths about childhood. Kids often see their siblings as larger-than-life, and Nelson captures that sentiment without overplaying it. The story doesn’t rely on grand battles or global threats; instead, it focuses on small moments—a whispered plan, a shared flashlight under a blanket, and the quiet thrill of knowing someone you love leads a double life filled with courage and responsibility.

More Than Entertainment

Children reading this book are offered more than just entertainment; they’re invited into a world where imagination and family love coexist beautifully. The message is clear: the people closest to us might hold astonishing secrets, and sometimes, being a hero isn’t about fighting dragons—it’s about caring for your family, staying true to your path, and showing up when it matters most.

Parents who read this with their children will also find the story relatable. There’s a tenderness in the way the younger sibling learns to see their sister not just as an older sibling, but as someone brave, complex, and worthy of admiration. It opens up conversations about identity, respect, and the many unseen ways family members support one another.

Illustrations That Bring the Story to Life

The illustrations are an integral part of the experience. Bright, expressive, and dynamic, they capture the stealthy movements of a young ninja alongside the cozy atmosphere of bedtime routines and shared secrets. Illustrator Camille Lowe’s artwork complements Nelson’s narrative voice, enriching the world without overwhelming it. The visual style balances fantasy with realism, helping young readers visualize both the ordinary and the extraordinary.
