This is no longer the novel where you become the hero, but the short story where you become a mathematician, a physicist and a geneticist. The Codex 97.1.128 is a hard science fiction work structured into three novels, exploring a fascinating hypothesis: what if the genetic code were not merely a blueprint for building life, but also an ancient, universal message? This message, hidden within the human genome by a civilization extinct for millions of years, becomes accessible only through binary conversion and mirror inversion of a specific fragment of the code. The simple mathematical sequence — 97, 1, 128 — points to a real star located in the Carina–Sagittarius galactic arm, at galactic coordinates l = 97°, b = 1°, r = 128 light-years. An isolated researcher discovers this codon anomaly, where the motif repeats, translates into images, becomes sound, then celestial coordinates, plunging the story into existential vertigo: are we alone, or simply forgotten in a discreet corner of the Milky Way, shielded from sight or chaos? Warning: this is a work of speculative fiction (hard SF), not a scientific document. However, all mathematical, physical and genetics sections presented within the story are designed to be verifiable and reproducible.
