Book 3, Children of My Heart (1977) - Gabrielle Roy
From the publisher:
“Set in the prairies in the 1930s, and rich with the author’s own memories of her time there as a young woman, this is a powerful story of an impressionable and passionate young teacher and the pupils, from impoverished immigrant families, whose lives she touches. Children of My Heart bears unforgettable testimony to the healing power love exerts on the wounds of loneliness and poverty.”
