I've just read Never Let Me Go by Kazuo Ishiguro – who wrote Remains of the Day, which I've not read because the movie with Emma Thompson and Anthony Hopkins was so devastating.
Never Let Me Go is quietly devastating as well. The reader is dropped in in medias res, having to decipher a collection of vaguely unsettling nouns – carer, donor, donation, completion – that become ever more unsettling as their meaning becomes clearer. It's wonderfully written, pulling the reader into a highly constrained, minutely detailed, unquestioned world. No one tries to escape, no one chooses how to live, everyone just waits for other people to release them. By the end, I was screaming the bookish version of "look out behind you!" at the characters. The anxious, overwrought tone of the book will haunt me for a while.
