Up and up and up! The star of Faster! Faster! and Higher! Higher! dons a construction hat for another soaring story about imagination.

A box full of blocks. A budding builder. What should she build? A dog kennel? A bridge? A skyscraper? Bigger, bigger! BIGGEST! But then... Boom! Boom! What’s that? Uh-oh ... it's the builder's little brother! This is an ode to imaginative play and creativity, fortified by Leslie Patricelli’s trademark playfulness and sense of humour.
