In The Blue Wagon, we follow young Heather as she drags her empty blue wagon down the sidewalk, eager to collect shiny stones and secret treasures. Each rock she finds—marble, crystals, a rainbow stone, and even a fossil—symbolizes something more than its surface value. Along the way, she meets kind-hearted Mr. Wiggledimp, learns about dinosaurs, and unknowingly stumbles into deeper truths about value, love, and burdens.

But as her collection grows, so does the weight she pulls—mirroring how even children begin to carry emotional loads. Through a simple story told in the voice of innocence, Karen R. Sullivan subtly teaches that what weighs us down may seem beautiful at first, but it can become exhausting when we carry it alone. The story gently opens a door to conversations about emotional weight, support, and the healing power of connection—making it as meaningful for adults as it is magical for kids.
