Her father, Armand Abécassis teaches philosophy and is a renowned thinker of Judaism whose thought permeated the Talmudic interpretation of Strasbourg.

[2][3] In several autobiographical novels, Éliette Abécassis declares to have been very influenced by the Sephardic religious environment and education, but to have also sometimes been suffocated by it and tried to emancipate itself from it on numerous occasions, especially during her youth.

She then wrote her first novel, Qumran, a metaphysical detective story that deals with mysterious murders linked to the disappearance of the recently discovered Dead Sea scrolls.

Her research lasted three years[6] and it paid off: Qumran was released in 1996 and immediately achieved immense success;[3] the book being translated into eighteen languages.

[7] In 1997, she began to teach philosophy in Caen and published L'Or et la Cendre, the mysterious story of the murder of a Berlin theologian, still with Ramsay editions.

In 1998, she wrote an essay on Evil and the philosophical origin of homicide: Little Metaphysics of Murder at the Presses Universitaires de France.

In 2002, her novel Mon père is published,[8] which tells of the questioning of an idyllic father-daughter relationship, while Qumran is adapted into a comic book by Gémine and Makyo.

[12] Le maître du Talmud, published in 2018, is a new historical-religious thriller, the plot of which is set in the kingdom of France in the thirteenth century, marked by the emergence of the Inquisition and religious fanaticism.

[13] Alongside the lawyer Marie-Anne Frison-Roche and the philosopher Sylviane Agacinski, she campaigned vigorously against surrogacy, which she likened to a practice of commodification of the body of women and reification of the child.

Éliette Abécassis has written books and articles on the status of women, which she defends in several associations, such as Le Corset invisible in 2007, with Caroline Bongrand.

Éliette Abécassis has also published a series of children's books: T'es plus ma maman, Je ne veux pas dormir, Il a tout et moi j'ai rien, Astalik fait ses courses et Je ne veux pas aller à l'école.
