Glory Goldenleaf, spy mouse extraordinaire, is assigned her first solo Silver Skateboard mission--to tail the evil rat Roquefort Dupont all the way to the Big Apple. He's paws-deep in a diabolical plot that could affect the international rodent community, and Glory's determined to find out what it is.

Joining Glory in the big city is fifth-grader Oz Levinson, who's a finalist in a junior bake-off contest. He and his friend D.B. will be competing against the best bakers in the country on live TV! But when Glory gets mouse-napped in Manhattan, Oz and D.B. need to stage a rescue mission. It will take all of their spy skills to save their favorite mouse, stop the rats' dastardly scheme--and pull off the perfect dessert.
