This is exactly what you want in a middle-grade graphic novel: fun, engaging, with just enough substance to feel good about handing it over. Katie's dealing with real stuff—summer boredom, friendship drama, wanting to earn money—and then BAM, 217 mysterious cats and superhero training.
The series has legs (four books so far, all well-reviewed) and hits that sweet spot between entertaining and enriching. It's not going to teach your kid calculus, but it models good problem-solving, entrepreneurship, and how to be a better friend when you mess up. The graphic novel format is clutch for reluctant readers or kids who just prefer visual storytelling.
Compared to other middle-grade options, this is solidly in the 'yes' column. It's got the whimsy of Dog Man without the potty humor, the heart of Raina Telgemeier's work with more action, and enough cats to make any feline-obsessed kid very happy. The New York Times called it heroic, School Library Journal loved it, and Common Sense Media confirms the positive role modeling.
Bottom line: If your kid is 7-12 and likes graphic novels, cats, or superheroes, this is a no-brainer. It's safe, fun, and actually worth the read.
