Rainbow Valley by L. M. Montgomery. Rainbow Valley (1919) is the seventh book in the chronology of the Anne of Green Gables series by Lucy Maud Montgomery, Anne’s wonderful, lively children found a special place all their own. Rainbow Valley was the perfect spot to play, to dream and to make the most unusual friends, like the Merediths. They were two girls and two boys who had no mother. What they did have was a minister father who was looking for a wife but so far had found nothing but heartbreak. Between the minister courting a young spinster and the escapades of the restless children, the town was bubbling with scandal. But in the end, the warmth and laughter of Anne of Green Gables taught all an unforgettable lesson of love.
