What is the theme of night calls by lisa fugard, what is the main element and what is the tone and mood of the story?

The story of the Night Calls by Lisa Fugard has quite a dark theme. The main element is family love between an estranged father-daughter relationship. The tone of writing was monotonous, perhaps that’s why it lacks reviews from different sites. The mood is very touching. It shows that there is really a deep, unconditional love among the family even after her mother left. In a way, they still carry on with their lives taking care of each other.
