Lucy Montgomery 
Rilla of Ingleside [EPUB ebook] 

In the continuing story of Anne Shirley, 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 with the Canadian Expeditionary Force. This book follows Anne from the age of 49 to 53.
