Anne of Green Gables is a 1908 novel by Canadian author Lucy Maud 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 on Prince Edward Island, Canada.
