Anne of Green Gables is a 1908 novel by Canadian author Lucy Maud Montgomery (published as L.M. Montgomery). Written for all ages, it has been considered a classic children's novel since the mid-twentieth century. Set in the late 19th century, the novel recounts the adventures of Anne Shirley, an 11-year-old orphan girl, who is mistakenly sent to two middle-aged siblings, Matthew and Marilla Cuthbert, who had originally intended to adopt a boy to help them on their farm in the fictional town of Avonlea in Prince Edward Island, Canada. The novel recounts how Anne makes her way through life with the Cuthberts, in school, and within the town. Since its publication, Anne of Green Gables has been translated into at least 36 languages and has sold more than 50 million copies, making it one of the best selling books worldwide. The first in an anthology series, Montgomery wrote numerous sequels, and since her death, another sequel has been published, as well as an authorized prequel. The original book is taught to students around the world. The book has been adapted as films, made-for-television movies, and animated and live-action television series. Musicals and plays have also been created, with productions annually in Europe and Japan.
