From New York Times best-selling author Mac Barnett, an uproarious early readerseries about a mischievous rabbit, a cranky old lady, and a lovable dog.

The Lady and Rex have a baseball game against the Big City Brats. Jack is not allowed to swing the bat, so he is told to be the Bat Boy. That is, until the Lady Town Ladies and the Big City Brats are tied. It's up to Jack to hit a home run, but on the way to home plate he spots some snacks....

Welcome to the laugh-out-loud and irreverent world of Jack, a new early reader series by New York Times best-selling and award-winning Mac Barnett.
