I read After Sappho for my James Tait Black project. It is experimental, written in short vignettes that jump around in time and from person to person. It tells the stories of lesbian women, mostly literary figures, trying to make a place for themselves. It begins in the late 19th century with women fascinated by the poet Sappho. Some of them study Ancient Greek, some dress like ancient Greeks or re-enact ancient plays, some travel to Greece.
The novel is vividly written in first person plural or in third person, at times slyly ironic, sometimes engaged in word play, often invigorating and with lots of sexual metaphors. It is interesting, telling of repressive laws against women, particularly in Italy, and reporting actual aggressively misogynistic “scientific” or political statements by men. It goes on to tell of the accomplishments and tragedies and love affairs of its protagonists, largely ignoring the men in their lives. For example, from this novel, you wouldn’t know there was a Leonard Woolf, just a Vita Sackville-West.
Although I found the novel very interesting at first, there were so many characters that I couldn’t keep track of them or remember which events happened to which ones. I could only track the ones I was already familiar with. For example, the novel begins and ends with Lina Poletti, even though she disappears about halfway through, so she is obviously important to Schwartz, but by the end I couldn’t remember her. I felt like I needed a chart.
And yet, I feel that with more character definition, I might have remembered all of them, but these short vignettes that tell of an activity or something they said didn’t really provide a cohesive picture to me of what the women were like.
So, I applaud this novel’s daring devices, but they didn’t really work for me.

I really liked the premise of this one, but I gave up on it for the same reason that you struggled: too many stories, with so many characters I’d never heard of and didn’t care enough about.
I’m glad it wasn’t just me!
That is probably why I have some problems listerning to this one. It does sound fascinating, but I think I need to read it.
I can imagine it would be even more confusing if you were listening to it.
