Two of the greatest heroes in children's literature, Tom Sawyer and Huck Finn, join forces in this classic tale from master storyteller Mark Twain. Tom and Huck are kidnapped by a mad scientist in a balloon-powered airship who plans to fly around the world then crash in flames - taking the boys with him. But when the madman falls overboard during a storm over the Atlantic Ocean, the youngsters are forced to use all their wits to save themselves from further perils aboard the runaway airship.
