For me, it was Expedition to the Baobab Tree, by Wilma Stockenström.
The plot is anachronistic, spanning decades or centuries and across many nondescript but very real locations. The narrator is meant to exemplify the experiences of countless people who have endured the same legacy of slavery and abuse across time and space in human history.
The last section of the story deconstruct one’s desperation for meaning and self-identity in the face of absolute solitude. I’ve never read another book like it.
Or people just don’t need to write as much, especially not in cursive since it only adds legibility problems.
