In book 13, someone has broken into the library and left it in a mess--worst of all, they've stolen one of the books! Kitty and her crew leap into action to track down the culprit--a pirate cat named Cutlass. Kitty soon teaches Cutlass the error of his ways, informing him that he doesn't need to steal books from the library--they can be borrowed! Having saved the day, Kitty, the cat crew, and Cutlass enjoy a rooftop story-time.

Join Kitty and her cat crew on the rooftops for a series of enchanting adventures by the light of the moon. Here, Kitty will discover that being a superhero is about more than using her special abilities--she must learn to be courageous too.
