Buster and Bo go on a vacation to the ancient, magical city where the streets are water and the buildings are palaces - Venice, Italy! Little does Bo know, though, that Buster is on a secret quest to track down the renowned Murano glass factory so that he can buy a replacement glass fish for the one he and Arthur broke at the Read home. During the course of his adventures in Venice and its lagoon, Buster learns all about this enchanting city where there are no cars and everything from mail delivery to buses is done by boat. Even though Bo considers himself a master map-reader, like so many tourists before them, the Baxters get hopelessly lost among the winding byways, palazzos, alleys and canals.
