In Vancouver graphic designer Bree Galbraith’s debut picture book, young Theo’s tale begins with a common childhood heartbreak: a balloon slipping from his grasp and floating away.

After watching the balloon disappear into the distance, Theo begins to wonder where it went. His father offers the fanciful notion that all lost balloons collect in the sky and hold up the moon. His more logical mother explains that the balloon likely popped when the air pressure changed. But big brother Zeke knows what really happened: the balloon drifted to Chicago (where all lost balloons go) and was picked up by a rather disenchanted Balloon Collector named Frank, who is so unhappy that he’s building a robot to take over his duties.  

Galbraith demonstrates an intimate understanding of a child’s inquisitive, innocent nature. While Theo continues to ask questions, he doesn’t hesitate to trust in his brother’s yarn, and he certainly doesn’t drag his feet when it comes to giving Frank some much-needed encouragement.

The fantastical storyline is enhanced by Isabelle Malenfant’s whimsical illustrations. With a hint of Quentin Blake and a dash of Antoine de Saint-Exupéry, Malenfant captures the story’s spirit, exemplified by a particularly striking illustration of a grey Chicago enlivened by colourful balloons that drift among the skyscrapers.

Once Upon a Balloon playfully teaches a couple of important life lessons. Children will be delighted as Theo persists (and succeeds) in trying to help Frank, and adult readers may be reminded of something too easily forgotten: that a childlike sense of wonder is something to be treasured.
