This "New York Times"-bestselling tale of magic, science, bravery, and adventure by master storyteller Gaiman and Emmy-winning writer Reaves is now in paperback. Joey Harker has always had a terrible sense of direction. One day he gets lost in his own town and walks right out of his universe.

A nine-year-old inventor is about to have her worst day ever in this laugh-a-minute mega-robot adventure! Molly should be doing her homework, but instead, she builds a robot to do it for her. The robot is pretty clever ... so clever that it decides to make another robot. Then that robot makes another one. Before long, an army of slightly-too-clever-for-their-own-good robots are running around town causing chaos. But when robot number one gets wind of Molly's plan to shut them down, the mechanical army set out to get rid of the humanoid once and for all. Now, Molly must race against time to stop the mega-robot invasion ... and hand in her homework!
