We were so EXCITED when this book was released. We have the whole set. Truly wonderful characters, a fast paced intelligent rhyme, and the theme of working together and gaining acceptance by using what you can bring to the game. Illustrations are bright and lively. Buy this book, you will have fun reading it to your children over and over again! Also buy, Goodnight, Goodnight Construction Site, Mighty, Mighty Construction Site & Construction Site on Christmas Night.
