A shock KO book that left me demoralized and this Sunday autumn evening. I faltered and suffered with me indignant while Mathilde of this calculator and perverse sadism. Again and crude way, Delphine De Vigan brings us outstanding in the maze of lonely and sad lives. After the story of a homeless with "No and Me" is the story of two SLF (No fixed light). The only downside to my idea of the difficulties of the characters superimposed, one is a widow at 30, the other has lost fingers. This was necessary given their already great torments? the author builds where it hurts: the solitude of beings even in a crowd and capitulation to adversity (a sadistic superior, cold as a marble mistress, a waterproof city to pain). Thank you madam for disturbing us in our little daily comfort and make us think about as real subjects.
