A young boy and girl find a sanctuary under an old shady apple tree. So do a lot of wild things--woodpeckers, insects, raccoons--and the children, though they might think they are alone, soon have many neighbors in the hollow tree trunk. The pictures are lively and warm, penciled with great detail and close observation of natural behavior.
The story, too, is detailed and thorough, helping explain the pictures with creative, understandable words. A carpenter bee, one of nature's most crafted homemakers, lays her eggs in the hole; a chickadee builds a nest; a raccoon hibernates; and the pictures offer a wonderful look into these otherwise hidden worlds.
