Kazuo Ishiguro and his family moved to England when he was 6 years old. He was educated in schools in England. He writes in English. You may read more about him in Wikipedia. He is probably best know for an earlier novel “Remains of the Day” which was made into a film with Anthony Hopkins.
My copy of “Never Let Me Go” was the paperback Vintage edition. I tell you this because I refer to page 81. If you know nothing about this novel (and I try to avoid spoilers) then you might not appreciate what is happening until you reach page 81 at which point the lightning strikes. After that the novel can seem many things: strange, creepy, grim, or quite possibly boring. Because I always try to give a book a fighting chance I plowed onward determinedly. Because the premise is so threatening I just had to find out what happens to the characters. At least be forewarned this much: do not expect fireworks. Finally for me the overwhelming emotion was sadness.
