Can one good deed from an ordinary girl change the world? It can when she's Ordinary Mary--an ordinary girl from an ordinary school, on her way to ordinary house--who stumbles upon ordinary blueberries. When she decides to pick them for her neighbor, Mrs. Bishop, she starts a chain reaction that multiplies around the world. Mrs. Bishop makes blueberry muffins and gives them to her paperboy and four others--one of whom is Mr. Stevens, who then helps five different people with their luggage--one of whom is Maria, who then helps five people--including a man named Joseph who didn't have enough money for his groceries--and so on, until the deed comes back to Mary. It's a feel-good story that inspires and celebrates a world full of ordinary deeds!
