“A posh building in rue de Grenelle (Paris), its days recounted from two points of view, one belonging to a cultured concierge, the other to a little rich girl with suicidal tendencies. Add some caustic humor, philosophical discourses, and an oversize adoration of Japanese culture and you have the ingredients of a novel that plays merrily with stereotypes, quotes Proust, Eminem, and Husserl, and has surprised everyone by remaining at the top of the French bestseller lists for months.”—D-La repubblica (Italy)
