Confidence is one of the most important qualities a child can develop. It helps them try new things, express their ideas, overcome setbacks and believe in their own potential. Yet teaching confidence isn’t always easy. Children can quickly spot when a lesson feels forced and stories that openly preach often lose the magic that makes them memorable in the first place.
The most powerful stories don’t tell children what to think. They allow them to experience a journey and discover the lesson for themselves.
That’s exactly what makes Ruben and the Curious Cosmonaut (The Great Disguise Series Book 1) by A R Marchant such a compelling read.
At its heart, this isn’t a book about confidence. There are no speeches about believing in yourself. No dramatic declarations about finding inner strength. In fact, the word “confidence” barely needs to appear at all.
Instead, readers meet Ruben, a thoughtful, creative boy who often feels more comfortable observing the world than standing at the center of it. He’s imaginative, kind and deeply curious, but like many children, he sometimes questions whether his voice matters.
When a school project doesn’t receive the recognition he hoped for, Ruben experiences something many young readers will instantly understand: the feeling of being misunderstood. It is not failure that troubles him. It’s the sense that nobody has quite seen what he was trying to achieve.
Then everything changes.
A visit to a mysterious costume shop called The Great Disguise leads Ruben to an extraordinary cosmonaut helmet and a magical journey through a mirror into a strange and beautiful world. There, among drifting structures, forgotten machines and a fading star, Ruben is faced with challenges that cannot be solved through strength or speed.
He must listen carefully.
He must think deeply.
He must trust his instincts.
Most importantly, he must keep going even when he isn’t sure he can succeed.
This is where the story quietly teaches confidence.
Ruben doesn’t wake up one morning transformed into a fearless hero. He remains thoughtful. He remains cautious. He still experiences doubt. But with every challenge he faces, he learns something important: confidence isn’t the absence of uncertainty. It’s the willingness to move forward despite it.
That message feels especially valuable today.
Many children grow up believing that confidence looks loud. They imagine confident people always know the answer, always speak first and never hesitate. Ruben and the Curious Cosmonaut offers a different perspective. It shows that confidence can be quiet. It can look like persistence. It can look like kindness. It can look like taking one small step forward when the outcome is unclear.
For parents, teachers and librarians, this makes the book far more than an entertaining adventure. It becomes a conversation starter about resilience, self-belief and personal growth.
For children, however, it is simply a wonderful story filled with mystery, imagination, memorable characters and the promise of adventure hidden behind ordinary doors.
And perhaps that’s the greatest achievement of all.
A R Marchant has created a story that helps children build confidence without ever turning the lesson into a lecture. Instead, readers grow alongside Ruben, discovering that courage, creativity and self-belief often arrive quietly and that sometimes the strongest heroes are the ones who never realized they were heroes in the first place.
