Nice work, in both languages! You're really flexing your creative muscles eh? :)
I wouldn't presume to critique the French and the English is excellent. I only wonder why you've been a bit more sparing in the English.
ie - why not a violent or maybe aggressive cancer?
...squander with idiotic zeal
Also, The Blind Herd sounds good but why not make the French title the same as the English. Les Moutons lèvent la tête or something?
/edit. Maybe that's the French title of the book?
//edit. Oh yes, so it is... :)
