Rilla of Ingleside is the final book in the Anne of Green Gables series, but was the sixth of the eight 'Anne' novels. This book draws the focus back onto a single character, Anne, and Gilbert's youngest daughter, Bertha Marilla 'Rilla' Blythe. It has a more serious tone, as it takes place during World War I and the three Blythe boys- Jem, Walter, and Shirley- along with Rilla's sweetheart Ken Ford, and playmates Jerry Meredith and Carl Meredith- end up fighting in Europe.
