This book is remarkable, in that with every page I read, I was more captivated.
For one thing, the author tells the story in a very interesting way: The story is narrated by two very different, but also very similar, characters. One is a 12 year old genius and the other is a 50-something year old concierge in the fancy hotel she lives in. So that's cool, but the writing style is what really got to me. Barbery gets very deep into some philosophical questions, that at many points I found confusing at first, but once I got into my "elegance of the hedgehog mood", I really enjoyed it.
