Patty's sure she's the only 10-year-old in the world who can't ride a bike. This summer, when she visits her grandmother and aunt, she's sure their surprise is going to be a bike she can learn on. The kind all the other kids have. Butoh, no!this bike is impossible! And her best friend has started a club without her! And the twins are in it!
Will Patty have the nerve to make summer turn wonderful? She would if she could...and she can!
