While it was not a big shock - he was sick for some time now, I am deeply saddened. We always had the next novel to look forward to; now there is less light in the world.
Ballardian corralles the tributes - Owen Hatherly and Mark Fisher (in Part 4) are characteristically thoughtful.
And Steven Shapiro beats me to the punch here. I think that Ballard's last four novels are a sort of auto-critique, especially the self-referential Kingdom Come which received horrible reviews. It is especially sad that Ballard's last novel (a painful, painful phrase) should have been so universally panned; somebody's sorry now, I should think.
