Like many, I bought this book after shuddered reading the Hedgehog. We see how Muriel Barbery is ripe, since its inception, his real literary talent is appreciated, its lexical richness, fineness and originality of his approach to the story. But it is clearly a tone below the hedgehog: the narrative technique is confused, not fully developed, laborious. There's no fluidity or the lightness of the hedgehog. It's interesting to understand the author of evolution, but less enjoyable as playing "themselves". Congratulations anyway!
