Rilla of Ingleside follows Rilla Blythe, the spirited youngest daughter of Anne Shirley, as she comes of age during World War I. Carefree and excited for her first dance, Rilla’s world changes overnight when war is declared, and the young men of her small Canadian town march off to battle—including her brothers and the boy she secretly admires. Left behind, Rilla must find her own strength, whether it's raising an abandoned war baby, managing the home front, or facing heartbreak and uncertainty.
