Be careful what you wish for. . . .

When new stepsiblings Milly, Michael, Jason, and Jess move to a town in the middle of nowhere, the last thing they expect is to find a magic book. But then they stumble upon The Genie Handbook, and their lives are changed forever. Each chapter in The Genie Handbook contains one of six stages of training to be mastered, and the kids are thrilled to begin their schooling—especially since once they become genies, they can wish themselves back to London and their old lives.

But then some of the wishes go wrong, and the magic starts to seem scarier. And when the kids discover a mysterious couple watching them covertly, they realize there's more to the handbook than they ever could have guessed.

If the children's greatest wish of all is finally granted, will their world change for better or for worse? Maybe sometimes it takes something even more powerful than a genie to reveal your true heart's desire.
