Thought this book had a cute cover. Unfortunately my local library doesn’t have it so I can’t give you a full book report and Amazon doesn’t say a whole lot more than this:
“Whoosh! Every day, the red blur goes whizzing by. Jackson needs to catch that scooter, even if he has to chase it all over town.”
Which is why I guess it’s a “Secret” Scooter Book:
