No, I haven't, but will definitely check it out. I did finally read Neal Stephenson's Seveneves before I started the Trisolaris Trilogy. I find them excellent at conveying the sense of vastness of space and time and how truly fragile human civilization is. In a way, this Notre Dame tragedy calls up the some of the same helpless (but not hopeless) feeling as reading about the existential dangers faced by humanity in these books.
