A bright, science-minded boy goes to the beach equipped to collect and examine flotsam--anything floating that has been washed ashore. Bottles, lost toys, small objects of every description are among his usual finds. But there's no way he could have prepared for one particular a barnacle-encrusted underwater camera, with its own secrets to share . . . and to keep. In each of his amazing picture books, David Wiesner has revealed the magical possibilities of some ordinary thing or happening--a frog on a lily pad, a trip to the Empire State Building, a well-known nursery tale. This time, a day at the beach is the springboard into a wildly imaginative exploration of the mysteries of the deep, and of the qualities that enable us to witness these wonders and delight in them.
