I actually quite enjoyed The Unconsoled even though it’s not considered to be Ishiguro’s “best work.” I think that memory (as a concept) is a pretty major theme in most of Ishiguro’s work and it features fairly prominently in The Unconsoled as practically every character in it has their own past and backstory that gets explored. The more digressive aspects of The Unconsoled help it more than hinder it, IMO.
