It is the truly fabulous sequel to the Caldecott Honor, The Red Book, a wordless book whose pictures tell the tale of a city-dwelling child who finds a red book in a snow bank, in which this child sees another child on a tropical island who is reading a red book about her. Through the pages of the original book, we see the city-dwelling child drop her book n the sidewalk as she sets off with a bunch of helium balloons to visit the friend she met in the book. This sequel begins exactly where the first book ends, with another child finding the dropped book. This new child in the same city connects with another child from the same island as the original, and this time the island child comes to visit the city (by means of pelican-powered dinghy). In the excitement of noticing his new-found book friend in person, our new lead character drops the book again, and we see it landing in a snow bank, where it ends, exactly as the first book began. Thus the two books circle round on each other.  Every school library should have both.
