That is the dream of all novelists-that one of their characters will become 'somebody.'
I don't think it is worth explaining how a character's nose or chin looks. It is my feeling that readers will prefer to construct, little by little, their own character—the author will do well to entrust the reader with this part of the work.
I consider books to be good for our health, and also our spirits, and they help us to become poets or scientists, to understand the stars or else to discover them deep within the aspirations of certain characters, those who sometimes, on certain evenings, escape from the pages and walk among us humans, perhaps the most human of us all.
