The novel is set in South Africa in the mid-1980s, during the era of apartheid.
An elderly classics teacher learns that she has incurable cancer.
She resolves to recount the final days of her life to her daughter, who left the country many years ago:

I tell you the story not so that you may take pity on me, but so that you may learn how things are.
It would be easier, I know, if the story came from someone else, if it were a stranger’s voice resounding in your ears.
But the fact is, there is no one else.
I am alone, the only one writing.
Do not pass it over, do not forgive easily.
Read everything with a distant eye

.
This declaration by the protagonist encapsulates the novel’s multifaceted meanings: the events, and above all the companions, of the old woman’s final days, the loneliness and nostalgia for the past, the exile from her daughter.
An alcoholic vagrant and a stray dog find shelter at the protagonist’s home; initially wary, but growing increasingly trusting, she takes them in, finding solace and friendship.
Meanwhile, the plight of two Black youths draws the elderly teacher into the grueling living conditions of the Black population and, above all, into the brutal repression of the Afrikaner police.
Upended by events that shatter a hitherto tranquil existence, the letter to her daughter changes in meaning: intended as a way to reinforce their bond, the woman instead finds herself swept into turmoil and uncertainty. Her love for her daughter grows more abstract and distant, while her feelings deepen toward those closest to her in suffering and in the face of death: the vagrant, the dog, and the two Black youths.
And a plea for love rises from the old teacher:

and this long letter, I say it now, is a plea toward the sunset, toward the west (the daughter lives in the United States) for you to return to me.
Come and hide your head in my lap as a child does, as you used to do.
I cannot live without a child, I cannot die without a child.
What I endure, in your absence, is grief.
I produce pain.
You are my pain.
This is an accusation.
Yes, I accuse you.
I accuse you of having abandoned me

It is a powerful, ancestral novel, dominated by classical themes typical of Greek tragedy—those of Aeschylus and Sophocles.
The relationship between mother and child is explored not in psychological terms, but by tracing it to an ineluctable destiny: the detachment of offspring from their parents.
The daughter’s flight from South Africa begets the mother’s exile, her solitude, and with it the awareness that she will not be remembered after death

let me go from myself, let me go from you, letting go of a house still alive with memories: it is a difficult task, but I am learning

Do not be afraid, says the protagonist, I will not seek you out.
It is not my soul that will remain with you, but the spirit of my soul, the breath, the movement of the air around these words, the faintest turbulence traced in the air by the otherworldly passage of my pen across the page your fingers now hold

Why read it? It is not an easy read, not least because the author frequently opens philosophical digressions, but the novel’s cosmic depth and the evocative power of many of its pages are well worth the effort.
