My favorite Kazuo Ishiguro title is The Remains of the Day. The novel is set in England where the protagonist, an older butler named Stevens, works at Darlington Hall. He falls in love with a co-worker, Miss Kenton, but he never tells her how he feels. Stevens keeps his feelings inside about many things, and he finds that he suffers because of it.
I really appreciate the narrative voice and perspective in the novel--Ishiguro captures the voice of the older English butler and the reader sympathizes with Stevens's problems with communication.
