The author's address to camp two young characters, actually quite extreme, is remarkable. He manages to describe them and make them live without the description turns to caracature nor the boy, gifted, autistic, marked by the abandonment of her little sister delayed nor the girl, anorexic and lame after an accident ski in the small enfance.Bref two lonely beings, almost antisocial and whose destinies cross, lose, come back, never melt. Wonderful character analysis, tough but fascinating. We dare not abandon reading!
