I don't think it matters how long you wait, general thoughts are the best people seem to do with this Author. This is the first book of his I have read, and I agree with those that say it is unlike anything they have read before.
I have never read prose that is so frenetic in it's pace, and to make the experience more interesting, each sentence is so engorged with words, that are carefully even artfully chosen, that dense does not begin to describe this Author's use of language. Once you become accustomed to the pace and richness of what he writes, he becomes readable. Umberto Eco comes to mind, but this Author is not as burdensome, you participate as a reader more quickly. I also love Mr. Eco's work; I just never find the reading comfortable.
His knowledge of his material is encyclopedic. He creates characters that are as unique and varied and sometimes eccentric, as any other Author I have read. And what does he create with this?
There is a group building "The Cavern", think of it as a very early Beta version of the Holodeck on The Enterprise. This is not a place for recreation; their goals are varied and constantly evolving. This room of no time, which is supposed to eventually be the perfect VR World, the perfect forecaster of whatever you like, Or for others an apocalyptic place, its potential too horrible to imagine.
All of this plays with another story in the background that superficially could not be less related, and this is probably the genius of the book. There are a number of Authors writing that try to be clever and original; they fail with the former as they lack the latter. Their stories don't hold up because you know the end, halfway or even less into the book. This time even when you think you know, even after the end has revealed itself, the book stays with you and you continue to sort out the dozens of thoughts and philosophies, which the characters from Countries as different as Armenia, and Ireland, and Korea bring to the story.
The book pulls all of your emotional strings, and most of your moral and ethical ones as well. If you find yourself immersed in this Author's writing you are in for one very enigmatic, puzzling, fantastical ride.
