That's a great story FRIENDSHIP pure and noble as we would like to know similar. I recognized the merits of Mrs Gavalda and even forme.Je do not understand all these negative reviews, when one identifies the character Billie, we forget to pay attention to vocabulary and take the essence of his feelings. Maybe some readers do not have enough projection or tolerance to accept to read a story about a "worldist quarter" in France. And yes it exists and in our country. I was shocked by the "Could do better" I read critically title. Anna thank you for this book, I have only one regret that of having devoured in one night
