From the acclaimed author-illustrator Joseph Kuefler, comes the third book in his popular Digger picture book series, about a crew of building trucks who befriend a caterpillar and witness its metamorphosis into a beautiful butterfly.

Digger and the other big trucks work all day, smashing and building and transforming their jobsite.

But when a caterpillar weaves its cocoon onto Digger’s bucket, he is forced to stop and be still.

In the stillness, Digger begins to notice the world beyond his worksite. And when the butterfly finally emerges, it’s clear that Digger and his friends have also been changed forever.

This book will include back matter which illustrates the stages of metamorphosis for young readers.  For Ages 4 and up.
