The first half of this 5 hour audio book hovered between around 1.5 stars for me, but I kept listening on the strength of a few very good reviews and the second half leapt up to 4.5 stars and almost made me cry, so I am splitting the difference with my rating. (I fully spoil the plot below, and I'd give this book a content warning for difficult pregnancies, abortion, and the death of a child). 

The book doesn't have much plot: a very self-absorbed woman spends all of her time in the Portal, which is like Twitter, but even more immersive. She rose to internet fame on the strength of a few very good memes, and now spends her time giving talks at prestigious institutions all around the world, apparently no longer needing to work. The first half the book is basically a tour through real and invented meme culture. Then, right at the halfway point of the book, the main character's sister gives birth to a baby with severe disabilities who is not expected to live more than a year. The whole family's attention is re-focused around the child, and the main character gives up pretty much everything else to make the child's short life as joyful and full as possible. This part of the story hits very hard, and it is clear the author is writing from personal experience of having loved and mourned a child. I wonder if less of the book could have been spent demonstrating how skewed the main character's priorities where before they were re-aligned, but the book is what is, and maybe another reader would be drawn in by literary equivalent of endless scrolling. I'm not sure I will recommend this book to anyone, but I am glad I listened to it.
