Excellent, but for a very particular audience. The prose has high expectations of the reader, which is not to say that those who don't enjoy the book are fools, lazy readers, etc. It's simply to say the drama here is largely internal and will not suit everyone. But the language is breathtaking. I point to a line near the end. The narrator is describing a nurse's sponge bath for his terminally ill mother:
"The eyes were done first, the nurse's hand moving from nose to cheek, as a tear would run."
The statement is precise, ruminative and poetic. If that line prods you, the book is for you.
