[A] charming and comedic debut. . . Fun and irreverent mysteries with relatable humor fill this charmer that highlights the value of friendship and being yourself. Highly recommended.
School Library Journal (starred review)

While her cases may not be as mysterious as Nancy Drew s or as challenging as Encyclopedia Brown s, debut creator Healy s ebullient would-be investigator Casey depicted as a pale-skinned, triangle-shaped 11-year-old with brown pigtails and a red dress is a welcome addition to the cadre of juvenile sleuths.
Publishers Weekly (starred review)

Delightfully silly, with humor aimed right at middle-grade readers and a few slightly more-mature sight gags that older readers will catch. The art is equally silly, with basic shapes, squiggles, and expressive eye-rolls working together to animate the small cast of characters. The case of the funny new graphic novel is closed!
Booklist

The mysteries are fun, but the highlight is the friends we ll make along the way.
