Ouch! I suppose you're the guy who came up with title? For me, the issue was that I didn't know what a "Grothendieck" was and the title doesn't give you any clues either; in fact it explicitly denies that any exist. It also flouts the convention for fanciful non-fiction titles, which is something like "Clever-or-poetic-part: plain description." Something like "A country of which nothing is known but the name: Grothendieck and mathematical motivation" would be better, I think.
