Trained in applied arts school, graphic design, and illustration, and later in design, Agnès Hostache worked for 8 years in major advertising agencies as an art director, then 12 years in interior design agencies. In 2015, she chose to fully dedicate herself to illustration and comic book writing.

She published her first graphic novel “Nagasaki” with Les éditions du Lézard Noir in 2019, which was officially selected for the grand jury prize at the Angoulême festival, for the FBDM in Montreal, and for the Landerneau prize from the Edouard Leclerc Foundation. This first book received the ADAGP – quai des bulles revelation award.

In April 2023, she published her second graphic novel “E 1027”, also with Les éditions du Lézard Noir, which received a warm reception from both the public and critics alike. “3”, published in 2024 by Matita, is her first children’s book.
