Except for his unusual name, Harry Houdini Marco is unremarkable in every way. While his namesake was the greatest illusionist of all time, Harry can't even catch a ball. He is on the verge of a long, boring summer--and he is dreading every moment of it. Then he meets a mysterious traveling salesman named Mr. Mazzeeck. But Mr. Mazzeeck is more than a traveling salesman, he's a wizard--at least, he claims to be. Before he leaves town, Mr. Mazzeeck gives Harry a bottle of magical oil, saying that the potion will give him wings. And to Harry's amazement, the oil works: He gets wings! Now he just has to figure out how to use them.
