Goodnight, Goodnight, Construction Site, by Sherri Duskey Rinker and Tom Lichtenheld, Chronicle Books 2011.
My son turned five about two weeks ago. He got a "Big Dig" from my husband's parents. He sits on the seat and he can dig holes in the sandbox with the big, construction-like shovel. All that is great, except he doesn't have a sandbox. I set him to work on the weeds in the garden -- with rather disastrous results.
A few days after his birthday, my son received this book from a friend of mine. He recognized the "Big Dig" right away, and immediately told me a story about a shovel and the moon and the stars. The story is great. The text is good, especially since it is a debut book -- the rhyming scheme goes off occasionally, but not irretrievably. The illustrations, however, are phenomenal.
The illustrations have a wonderful retro feel; they are soft, but bright and friendly, and with a healthy dose of humor. In all, my favorite kind of illustrations.
