The identity crisis is one of the major themes in the novels of Isabelle Hausser, particularly in these four novels '' The magicians of the soul'','' A family comedy'','' The kids' table’ 'and ''The passage of the shadows''. In the fictional universe of the author, her characters are continuously questioning both their identity and the world around them. They fall into a distressing situation and are upset when they discover the inevitable demolition of their former self-image, which they had never doubted before. From this moment, the confidence of these characters no longer exists. People face an unstable world full of doubts where they “will never know the whole truth” and they must live with “the knowledge that they have not understood”. So they become sometimes pitiful and melancholy. Moreover, in her novels, Isabelle Hausser remarkably emphasizes the process of understanding in her characters their identity crisis and the hope of recognizing their identity through friendship, music and especially the attitude of accepting life as it is. This idea could be considered as a little wisdom in the melancholy novels of Isabelle Hausser.
