Summary:  Between the end of day and the fall of night is the blue hour.  Blue animals from around the world are shown as they slow down for the night, or start to wake up if they are nocturnal.  A blue fox wanders through the Arctic, while poison dart frogs croak to each other from their water lilies.  Forget-me-nots, bluebells, cornflowers, and violets fill the night air with their fragrance.  As a blue whale surfaces, the last of the blue light fades, and the world moves into darkness.  Front endpapers identify 32 different shades of blue, and the back ones show where all the animals from the book live on a map of the world.  42 pages; ages 4-8.

Pros:  The stunning illustrations, almost all in various shades of blue, are worthy of Caldecott consideration. Combined with the soothing text, they make a perfect bedtime book.

Cons:  It would have been nice to have a little information on the different animals at the end of the book.  What, for example, are vulturine guineafowl?
