The Pollyanna Series: Pollyanna & Pollyanna Grows Up

Pollyanna is a best-selling 1913 novel by Eleanor H. Porter that is now considered a classic of children's literature, with the title character's name becoming a popular term for someone with the same outlook. The book was such a success that Porter soon produced a sequel, Pollyanna Grows Up (1915). Eleven more Pollyanna sequels, known as "Glad Books", were later published, most of them written by Elizabeth Borton or Harriet Lummis Smith. Further sequels followed, including Pollyanna Plays the Game by Colleen L. Reece, published in 1997.
