To be honest I really appreciate the eclectic range of recommendations, even if it leads in many directions at once.

As to "more specific requirements" I guess I am mainly interested in pessimist sf, horror sf and dystopian fiction. This is what I feel speaks most directly to me.

To my knowledge Thomas Ligotti has only written a single sf story - "The Nightmare Network" - which I have no problems seeing in continuation of the above.
