Once I finish Vertigo (likely this evening), I will only have one more Sebald novel remaining to me, The Emigrants. Few authors will have left me more disappointed upon exhausting their novels than Sebald, although I find it impossible to believe that a second reading of The Rings of Saturn won't prove at least as good as the first.
I say this for two reasons. First, because I read Rings three years ago, when I was a much different reader. I don't think I could possibly approach a book like The Rings of Saturn in the same way now, and combining everything new I would see with everything I've forgotten in the intervening three years would create a very fresh experience.
And second, I also say this because Sebald's four novels are very similar in terms of approach, style, and theme, and so a re-reading of Rings after finishing the other three books would be far, far less naive than my original reading. I think so many things would jump out at me that I missed the first time, and I'm curious to see what phrases my underlining pencil originally managed to alight on.
I'm afraid, though, that re-reading Austerlitz (the second Sebald I read) wouldn't be nearly as fresh of an experience as re-reading Rings, largely because the reasons cited above don't hold for that book. It's strange to say, but from Austerlitz on I've rigorously marked up my Sebalds with a pencil, and I feel so connected to each of his books while I'm reading each that it's difficult to imagine coming back to any one of them and finding something the feels wholly new.
