The illustrations are really charming, but the story is a bit flat.  It tells of a young girl (about age 6 give or take a couple years?) riding the bus by herself for the first time, to go visit grandma.  Who let’s a kid that young ride a bus by themselves?  Now granted, it’s obviously not meant to be taken seriously, as all the other passengers on the bus are animals dressed as people, but still.  The text is mostly just a ramble of the girl’s thoughts, and the story is mostly told through looking at the details of the pictures, and that is mostly just a story of watching the different characters come and go.  At the end of the ride, we see the girl connect with her grandma, proclaiming that she’s got so much to tell.  But really not much happened.
