Sandra Cardona is a Spanish illustrator living in Barcelona. She began drawing at a young age, participating in numerous art contests, before going on to study at the prestigious Joso School, where she perfected her detailed style. Her passion for fantasy movies and architecture led her to create her first graphic novel in 2018, titled "Bouillon," alongside writer Olivier Milhaud (Soleil). Then in 2019, during a residence in Quebec, she began work on "Devil on Her Shoulder," a graphic novel infused with magic and sorcery, created together with scriptwriter Cédric Mayen. The enhanced edition was released in 2023 (Dargaud; Europe Comics in English).
