The construction site is alive with personified machines in this engineering-minded bedtime story. It’s a brilliant collaboration by this married author/illustrator team, as pictures and words make us feel the deep joy and satisfaction that hard work brings! On top of that, we get our curiosity addressed as so often we see these big trucks on the side of highways and in construction sites not knowing much about them. This book teaches specific aspects of each machine including purpose and parts , all in a rhyming soothing text. Children can relate to the bedtime rituals described as these vehicles wind down from a long day of hard work-play. What a winning picture book for every child’s library
