First published in 1947, In Due Season broke new ground with its fictional representation of women and of Indigenous people. Set during the dustbowl 1930s, this tersely narrated prize-winning novel follows Lina Ashley, a determined solo female homesteader who takes her family from drought-ridden southern Alberta to a new life in the Peace River region. Here her daughter Poppy grows up in a community characterized by harmonious interactions between the local M tis and newly arrived European settlers. Still, there is tension between mother and daughter when Poppy becomes involved with a M tis lover. This novel expands the patriarchal canon of Canadian prairie fiction by depicting the agency of a successful female settler and, as noted by Dorothy Livesay, was "one of the first, if not the first Canadian novel wherein the plight of the Native Indian and the M tis is honestly and painfully recorded." The afterword by Carole Gerson and Janice Dowson provides substantial information about author Christine van der Mark and situates her under-acknowledged book within the contexts of Canadian social, literary, and publishing history.
