Professor William Waterman Sherman just wants to be alone. So he decides to take a year off and spend it crossing the Pacific Ocean in a hot-air balloon - the likes of which no one has ever seen. But when he is found after just three weeks floating in the Atlantic among the wreckage of twenty hot-air balloons, naturally, the world is eager to know what happened. How did he end up with so many balloons ... And in the wrong ocean?
For ages 10 to 12.
