Gloria is thrilled when she goes to the store to buy an onion and meets Dr. Grace Street, an astronaut. It’s there that Dr. Street tells Gloria to have confidence in herself and that the big things aren’t always as big as they seem. But Gloria doesn’t really understand Dr. Street’s advice. Right now her problem seems gigantic. It’s the beginning of fourth grade and Gloria can’t do anything to please her teacher, Mrs. Yardley, who roars and hisses like the Dragon of Doom. When Gloria writes a report about meeting Dr. Street, Mrs. Yardley doesn’t believe her. Gloria knows she’s telling the truth. How can she prove it?
