Anne of Windy Poplars, also published as Anne of Windy Willows in the UK, Australia and Japan, is an epistolary novel by L. M. Montgomery. First published in 1936 by McClelland and Stewart, it details Anne Shirley's experiences over three years teaching at a high school in Summerside, Prince Edward Island. The novel features a series of letters Anne sends to her intended, Gilbert Blythe, who is completing medical school. Chronologically, this book is fourth in the series, but it was the seventh book written.
Anne of Windy Poplars tells about the three years between Anne's graduation from Redmond College and her marriage to Gilbert Blythe. Anne has taken a job as the principal at Summerside High School, where she also teaches. She lives in a large house called Windy Poplars with two elderly widows, Aunt Kate and Aunt Chatty, plus their housekeeper, Rebecca Dew, and their cat, Dusty Miller. During her time in Summerside, Anne must learn to manage many of Summerside's inhabitants, including the clannish and resentful Pringle family, her bitter colleague Katherine Brooke, and others of Summerside's more eccentric residents. Additionally, Anne befriends the young and lonely Elizabeth Grayson, a motherless member of the Pringle family who lives next door to Windy Poplars. At the end of the novel, Anne departs Summerside, returning to Green Gables and Avonlea for her wedding to Gilbert. Upon her departure many of the town's residents express that they will greatly miss her as they have grown very fond of her or have been helped by her, including Katherine Brooke and Elizabeth Grayson.
