Novels which (gloomily/ambiguously) look towards the end of the twentieth century/start of the twenty-first…

I know this is a niche request, but here goes…

I'm looking for fiction written towards the end of the twentieth century which deals with the anxiety towards the start of the new century, with a fin de siècle feel. Think Ballard, for instance.

The best comparison I can make is David Bowie's album Outside, with its concern with the clock of the twentieth century ticking away. He said:

'Oh, I've got the fondest hopes for the Fin de siècle. I see it as a symbolic sacrificial rite. I see it as a deviance, a pagan wish to appease gods, so we can move on. […] We have this panic button telling us it's gonna be a colossal madness at the end of this century.'

Basically, any books – dystopian, sci-fi, literary fiction, horror – which are concerned with this kind of Y2K/survivalist/dour or interrogative mood. Even a novel dealing with the Y2K bug would be what I'm looking for.

Thanks!
