“"Through these letters, I don't talk about illness or death, but about life, about the things that happen, that life brings and takes away. I always like to say that we've been taught a saying, 'where there's life, there's hope,' and I understand it completely the other way around; I think that as long as there's hope, there's life, whatever form it takes and in whatever dimension we want to consider it."

Surgeon Sandra Díaz Sierra, affiliated with the Mammary Pathology Functional Unit at Hospital de Sagunt, has launched her debut graphic novel, Numbered Letters, an epistolary work exploring grief and life through thousands of personal letters.
The author, renowned for her medical profession, showcased her artistic side in the capital of Camp de Morvedre with the publication of Numbered Letters (SaludArte Ediciones). This graphic novel is built upon more than 4,800 letters that Díaz wrote starting from August 2, 2012, following the death of her best friend, Laura, due to breast cancer.
Sandra Díaz, who identifies as an artist before a doctor, has been illustrating and writing throughout her life. Her current work, which features over 40 selected letters, aims to weave a narrative that explores her epistolary relationship with her friend and how she has navigated the grieving process over the years.
From a young age, Díaz balanced her two passions: art and medicine. Following her father's advice, she prioritized her medical career but never abandoned her artistic calling. Since 2018, her literary and graphic trajectory has seen significant development.
Currently, Sandra Díaz is already working on two new literary projects. One is a graphic poetry collection, created in collaboration with fellow doctor and writer Magda Querol, and the other will be her next graphic novel, which will explore motherhood from various angles, promising an intimate and honest examination of the subject.
