On a boring day, on a dull street, Sebastian sat high atop his roof - something he was never supposed to do. When he launched himself into the air in his balloon made of Grandma's afghans and patchwork quilts, his journey took on a life of its own and his boring day turned into the adventure of a lifetime. From award-winning author/illustrator Philip C. Stead, comes another timeless adventure with his trademark whimsical illustrations and an unwavering spirit.
