Set almost a decade after Rainbow Valley, Europe is on the brink of the First World War, and Anne's youngest daughter Rilla is an irrepressible almost-15-year-old, excited about her first adult party and blissfully unaware of the chaos that the Western world is about to enter. Her parents worry because Rilla seems not to have any ambition, is not interested in attending college, and is more concerned with having fun. (In an aside, it is revealed that Marilla has died; her date of death is not specified but Rilla states it was before she was old enough to know her very well.) Once the Continent descends into war, Jem Blythe and Jerry Meredith promptly enlist, upsetting Anne, Nan, and Faith Meredith (who Rilla suspects is engaged to Jem). Rilla's brother Walter, who is of age, does not enlist, ostensibly due to a recent bout with typhoid but truly because he fears the ugliness of war and death. He confides in Rilla that he feels he is a coward. The enlisted boys report to Kingsport for training. Jem's dog, Dog Monday, takes up a vigil at the Glen train station waiting for Jem to come back. Rilla's siblings Nan, Di, and Walter return to Redmond College, and Shirley returns to Queen's Academy, leaving Rilla anxiously alone at home with her parents, their spinster housekeeper Susan Baker, and Gertrude Oliver, a teacher who is boarding with the Blythes while her fiancé reports to the front.
