[12] Catherine Dufour wrote many short stories in the fantasy genre, such as L'accroissement mathématique du plaisir, which describes the extreme emotion one can feel when faced with a work of art,[13] and L'Immaculée Conception, inspired by her experience of pregnancy[14] and winner of the 2008 Grand Prix de l'Imaginaire.

[16][17] In 2009, she set her novel Outrage et rébellion in a world somewhat similar to that of Le goût de l'immortalité in 2320 Western China, to tell the story of Marquis, who invents angry music to unite the students of his boarding school against their supervisors.

[18] In the Masterton Prize-winning fantasy novel Entends la nuit, published in 2018 and described as radical and original, Catherine Dufour tackled the theme of a powerful man falling in love with a woman of modest condition, in a story where suspense rubs cohabits with eroticism.

[19][20] Her two collections of short stories, L'Accroissement mathématique du plaisir (2008) and L'Arithmétique terrible de la misère (2020) confirmed her status as a benchmark writer, capable of expressing herself in all genres.

[13] In 2020, she published Au bal des absents, described as a ‘fantastic thriller that virtuously combines gothic frights and ultra-contemporary anxieties’.
