Is it worth living for more than a hundred years? Will artificial intelligence be used to prolong human life and aspire to immortality? Today, artificial intelligence and new technologies are rapidly changing our daily lives, how we relate to each other, and our rituals, symbols, and expectations. It has provoked great interest and a cross-impact of societal enthusiasm and fear. With exceptional clarity and lucidity, the novel THE BRIEF, with suspense, tension, and unexpected twists and turns, addresses a crucial and borderline concern that many readers question: the tantalizing pretension of using artificial intelligence and biotechnology to prolong human life and delay the arrival of death as long as possible. It invites the reader to reflect on a profound and defining theme of human beings: their finitude. The plot deals with the emotional journey of the protagonist, Pedro Romero. His psychological arc through the experience of living as a refugee with his parents on Icaria, a Greek island, during the Tragic Decade and the Absurd War; the three decades of research on how to delay cellular aging; the death of his wife for having applied the first version of his Youth Injection; his parents' trip to Antarctica; his ambition to have the formula for eternal youth to win the Vanguard Award in Biomedicine; the commercial dispute of the regional blocks to control his discovery; the harassment and accusations of corruption and murder of his wife by prosecutor Leo Soto; the trial and sentence of a robotic judge with artificial intelligence; the rejection of his daughter; the platonic love of his assistant Lila; his seclusion and the gradual acceptance that the Youth Injection he discovered is limited because there are a thousand ways to die and that life is finally beautiful, but fleeting.
