From a three-time Newbery Honor author: Harry Houdini Marco had it hard enough as a normal clumsy twelve-year-old—but growing wings made it even worse.  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. This book features an extended biography of Zilpha Keatley Snyder.

So Audrey keeps her writing a secret. That is, until she meets a mysterious old woman who seems able to read her mind. Audrey is surprised at how readily she reveals her secret to the woman.

One day the old woman gives Audrey a peculiar bronze pen and tells her to "use it wisely and to good purpose." It turns out to be just perfect for writing her stories with. But as Audrey writes, odd things start happening. Did Beowulf, her dog, just speak to her? And what is that bumping under her bed at night? It seems that whatever she writes with the pen comes true. However, things don't always happen in the way that she wants or expects. In fact, it's quite difficult to predict what writing with the pen will do. Could the pen be more of a curse than a gift? Or will Audrey be able to rewrite the future in the way that she wishes---and save her father's life?
