How did you feel it compared with some of his other works? Personally I enjoyed it, but to me it wasn't quite on the same level with some of his other books like the buried giant or remains of the day.
Kazuo Ishiguro's entire career revolves around memory: remembrances, sometimes unreliable, and always moving. If you like Ishiguro can I recommend W.G. Sebald? Rings of Saturn is like nothing I've ever read before.
