At the start of the 20th century, James Piper sets fire to his dead mother’s piano and heads out across Cape Breton Island to find a new place to live. Working as a piano tuner, he meets and eventually elopes with 13-year-old Materia Mahmoud, much to the anger of her wealthy, traditional Lebanese parents. James, madly obsessed with Materia, impregnates her, and then becomes increasingly frustrated and confused by her resulting strange behavior. Materia gives birth to their first daughter, Kathleen, and James subsequently becomes disgusted with his once intriguing wife, finally realizing that he actually married "a child". Materia regrets marrying James, and does not take to the child, as she believes her daughter's relationship with James to be revolting. James, however, is swollen with pride over his beautiful daughter, and spends his time ignoring and neglecting Materia while spoiling and smothering Kathleen. Through the eyes of James, his life is perfect, aside from his wife. According to the town folk, however, something appears to be seriously wrong with the Piper family. Materia is taken in by the kind neighbor Mrs. Luvovitz, who teaches her to sew and cook. Materia misses her old life and her family who have since disowned her. She grows to hate James and their daughter Kathleen.
Materia senses danger in James' obsession with their daughter and sees it as her duty to keep him distracted and occupied (especially in the bedroom), lest his affection for the young girl take an unnatural turn. Though his fixation on his eldest daughter is all encompassing, James eventually impregnates Materia three more times in quick succession. She gives birth to three girls, Mercedes, Frances and Lily, only to have newborn Lily die a crib death shortly after. She is from here on in the novel referred to as "Other Lily". The novel then explores the girls' relationship with their troubled father; their secretive, silent mother; and friendships that grow between them as they try to figure out their family's strange and mysterious history. As Kathleen grows older, she is perceived by her schoolmates as snobby, and they turn against her. Her father James is her only friend, and when he travels off to war, Kathleen is crushed. James, however, knows that he must leave Kathleen, as he has found himself increasingly attracted to her sexually. To him, enlisting is a way of beating "the devil."
