What's a girl to do when her parents won't let her get a puppy? If she's fifth-grader Billie Stoner and has a baby-sitter who also happens to be a teenage mad scientist, she can make her pet turn invisible! But Billie soon finds that keeping her new dog, Harry Houdini, under wraps isn't as easy as she had hoped-especially in her tiny Manhattan apartment. To begin with, he still smells like a puppy, feels like a puppy, and worst of all, sounds like a puppy. There are only so many times Billie can pretend to be barking before her parents thinks she's going crazy! And with her evil classmate, Alissa, catching on to the secret, just how long can Billie keep Harry concealed?
