What is the theme in The Liars' Club by Mary Karr?

Dysfunctional family life is a theme in the book. The Liars' Club is in many ways a grim story of the disruption of family life caused by a quarreling husband and wife, and a mother's alcoholism and mental instability. Although the devastating effect of this behavior on the children is apparent everywhere, especially in the aggressive behavior of Mary, it is not the main theme of the memoir. The main theme is the endurance of familial love in the worst of circumstances. The bonds generated by blood ties, even when put under tremendous strain, exercise a continual hold on the emotions and loyalties of the characters in the memoir.
