Jenny isn’t your average babysitter. She has a secret superpower—she can understand baby talk. (A pretty lame superpower for a middle schooler, if you ask her.)

Rosie isn’t your average baby—she’s the most brilliant (and devious) detective in town.

Jenny would rather do anything besides babysit. But the money she raised for her dance team has been stolen—and Rosie is sure she can crack the case.

This itty-bitty investigator and her babysitting backup have no time to waste—there’s a mystery to solve before nap time! And with all the humorous antics and endless fun of Katie the Catsitter, plus the feel-good middle grade heart of Click, the journey is sure to have plenty of surprises along the way.
