Nix Baines is seventeen years old, and she is displaced and alone. Neglected by her workaholic mother, lacking friends, and haunted by vivid manifestations of her own unexplored emotions, her life seems to be spiralling towards destruction and self-hate. However, there is one place in her small world where she feels safe and secure: the home of Mrs. Langlois, a mysterious older woman whose quirks and vulnerabilities seem to mirror Nix's own. More connected than either of them can possibly know, the two women launch into a turbulent relationship that exposes the deep, intergenerational wounds of family and societal pressure. Battling respectively on the existential edges of adulthood and old age, Nix and Mrs. Langlois must learn to coexist in order to share the internal wisdom that can heal them both. Deeply emotional and filled with the subtle, raw details of what it is like being a lonely human in a world of expectations, Mrs. Langlois' House is a powerful story about overcoming fear and opening one's heart.
