I really like the idea of this wordless picture book. A boy hides a box (the cover of which looks a great deal like the cover of the book) filled with trinket treasures and a map in the attic of what looks like a boarding school. Years later, the box is found by three kids who use the map to sneak out and go to Seahorse Pier. I was a little surprised to find kids from the past still playing at the pier, and then suddenly to see two more kids discovering the box, but I think it would inspire repeat readings by young ones.
