In a few novels, like Gilda Stambouli souffre et se plaint (2002)and Un Baiser froid comme la lune (1983), Jacques takes her characters from Egypt to France and Israel where they face issues of acculturation.

Jacques's characters confront hostility, humiliation, conflicted ideologies, political instability, and cultural alienation.

The novels explore the conditions under which Jews lived in Egypt in the years and days before their peremptory expulsion; the most developed cases are Lumière de l'oeil, L'Héritage de la tante Carlotta, Les Femmes avec leur amour, and the tragic La Descente au paradis.

In her novels, Jacques describes the suffering and humiliation experienced by both Jews and Muslims and shows both perspectives.

Alongside her novelistic production, Jacques has been involved in French theatre, radio, and the press.
