La saga de los longevos 1. La Vieja Familia by Eva García Sáenz de Urturi.

In The Old Family, the opening volume of the saga, we meet Iago del Castillo — a “longevo” of 10,300 years whose life spans epochs. One morning, he awakens in San Francisco, far from his ancestral home in Santander, with no memory of his name and no recollection of the mysterious investigation for which he travelled. The key question: what makes him and his family immune to ageing? Iago’s father Héctor refuses to reveal their secret, but his siblings Jairo (a fierce Scythian of 3,000 years) and Kyra (a Celtic exile of 2,500 years) are determined to build a new line of immortals—tired of burying their own children across centuries. Meanwhile Adriana — archaeologist specialising in Prehistory — returns to Santander to investigate the tragic suicide of her mother fifteen years earlier. An irresistible attraction develops between Iago and Adriana, though both resist its pull. Eva García Sáenz de Urturi weaves thriller, ancient mystery and emotional drama into a narrative where time becomes a character. With 480 pages of fast-moving plot, the saga blends investigation, family legacy and the cost of living beyond time. Ideal for readers who enjoy speculative fiction rooted in history, immortal protagonists, and epic stakes. This hardcover Spanish edition is the first part of a trilogy, published 2024 by Editorial Planeta.
