The Children of Mary follows the lives of three generations of Ukranian women on the prairies, focusing on the relationship between two sisters, Sonya and Kat, and the mysterious events of their childhood. As teenagers in the 70s, Sonya and Kat are trying desperately to be hip in the Ukrainian ghetto of North End Winnipeg. They experiment with everything from religion to marijuana, against a backbeat of Abba songs, Olivia Newton ballads, and endless reciting of the rosary. After her sister dies under mysterious circumstances, Sonya spends the next decade trying to figure out why. As she relocates to Toronto and creates a new identity for herself, her grandmother, Maria, moves backwards into memories of the Depression, her husbands radical politics and her own attempts to heal the scars of immigration and poverty through herbal remedies and the occasional clumsy attempt at witchcraft. Moving back and forth in time from the 1930s to the 1990s, the novel traces a familys journey from the old world to the new, from the Manitoba prairies to the queer feminist underground of Toronto, amid a complex web of secrets, half-truths and magic spells.
