It's summer and Katie is bummed that she can't go to summer camp with her friends. In order to try and pay to go, she starts working odd jobs. The only job that really sticks with with Madeline, a woman who has her watch her 217 cats. These aren't ordinary cats though: they can sew, use the computer, 3D print, and whole lot more. As the summer progress, Katie begins to learn more about herself, Madeline, and the cats.

This was an adorable and fun graphic novel. I loved Katie and all of the cats that she watched. It was a good blend of a friendship and growing up story as well as a superhero fantasy. I also very much liked the art style and color palette. This is going to really appeal to fans of Raina Telgemeier, Svetlana Chmkova, and Ben Hatke. This is one of my favorite graphic novels I read this year. I cannot wait for it to come out so I recommend to a wide range of readers.
