Well, I have to disagree regarding Seveneves. I was always a Stephenson fan, until I tried to read that book. Gave up in part three. It also left a sour taste, which resulted in me no longer caring about further books from him.
Yeah, it’s where I stopped as well. Although honestly I should have stopped when it became clear the Baroque cycle was just going to be him talking about stuff he found interesting with no coherent narrative.
I had Quicksilver as audiobook on a mp3 player during my 2 month trip through south america in 2006. Found the history lessons kind of interesting, but never managed to finish the book despite having a lot of time on my hands. Its just too fucking long winded without a real narrative. Apparently it was more interesting to sit still in a bus driving 48 hours through Peru, then to listen to this long-winded never-ending story...
