Henry Huggins #2: Henry and Beezus by Beverly Cleary (1984)

All Henry Huggins can think about is owning a bicycle, especially since that big showoff Scooter McCarthy has one.Henry decides he'll earn the money to buy his own bike...and that's when the fun begins. Selling bubble gum to all the kids at school brings Henry plenty of trouble, but very little money for his bike fund. In fact, it takes Henry's friend Beezus--who is pretty sensible for a girl--to turn the most humiliating situation of Henry's life into a real business success.
