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.

If I'd had this book as a kid, I would have read it again and again. There are so many subtly funny moments in this book. Katie is just a girl living her regular life, wishing she could go to camp with her friends... and she happens to live in a city of superheroes and villains, but it doesn't affect her day-to-day at all. She gets a job catsitting - for 217 of the smartest cats ever. A lot of little moments are so silly and fun. There's also an underlying theme here of a girl who is being raised by a single mom who can't afford to send her to camp, and there's a really genuine way of showing Katie's pain at knowing she doesn't have as much money as her friends and feeling too proud to accept money without working for it.

My only issue with this book is the way Bethany stopped being as good a friend when she went to camp. There seemed to be a plot point leading up to why this happened (suggesting she wasn't getting Katie's letters), but it never really came to anything. I think the middle grades trope of "friend goes away for a week or two and they suddenly change" is a little old. Hoping it'll be addressed in the sequel!
