Book excerpt: In this extraordinary Caldecott Medal winner and New York Times bestseller by David Wiesner, a beach day is the springboard to a wildly imaginative exploration of fantastical mysteries of the deep—and of human connections through time. A young boy comes to the beach eager to collect and examine flotsam—anything floating that has been washed ashore. But nothing among his usual finds compares with the discovery of a barnacle-encrusted underwater camera with its own secrets to share...and to keep. Meet unexpected underseas denizens and enter fascinating worlds within worlds in this entrancing celebration of imagination, creativity, and the impulse to share that which delights and amazes us. A beautiful picture book by a master of the form, David Wiesner, who has been awarded the Caldecott Medal three times and the Caldecott Honor twice.
