When there is absolutely nothing left to do sitting in your room, the best solution is to build a hot air balloon and take to the sky. Sebastian gathers his supplies, crafts a patchwork balloon, and floats up from his roof in search of an adventure. As you drift higher and higher alongside Sebastian, you will encounter a world of wonderful surprises. The sky is full of unexpected friends, including a bear, a very tall bird, and three elderly sisters knitting a massive blanket. Together, this unusual crew navigates the clouds and embarks on a whimsical journey that goes perfectly, playfully wrong. This enchanting and visually stunning story celebrates the boundless power of a child's imagination. It is a gentle, dreamlike flight that proves the best adventures are the ones you build yourself from the comfort of your own home.
