I registered just for this, and I have a feeling it's stating the obvious but, what about Kafka?
I don't read much fiction, but I truly enjoyed
The Trial and
Amerika. I have
The Castle too, but as of yet not got round to reading it. His style may be an acquired taste, but I find it very stimulating. Some translations are better than others, though which exactly I don't recall.
Coincidentally was recently in Prague, took a photo of his street (and building)!
Hope this might be helpful
