Caesar is a large white dog with a great many black spots. Or is he a large black dog with even more white spots? That's the trouble: he doesn't know which, and though nobody in the family seems to care, he won't rest until he uncovers the truth. So off he traipses, beseeching one animal after another to find out what color he is, basically. From celebrated poet Maxine Kumin comes a doggedly quizzical hero, brought comically to life by Alison Friend's expressive watercolors -- a lovable picture-book character who ultimately learns that it's not what's on the outside that counts.
