It's half novel, half related series of 9 short stories, but Accelerando is great. The Martian by Andy Weir (movie based on it) was quite good. Daemon I think also qualifies, though it's SF dressed up as a thriller. Oh, Blood Music by Greg Bear probably counts? Except maybe the ending? Tempted to mention The Diamond Age, but not sure that qualifies as "Hard", though closer than some other Stephenson maybe...
