An ordinary exploration mission. A stellar system that should never have existed. And a survival whose price no one yet understands. When the exploration vessel Niña is sent beyond charted space, the crew expects a routine mission. Collect data. Observe. Return. But something's wrong. Instruments react incoherently. Trajectories no longer follow known laws. And a diffuse presence seems to haunt the void between stars. The crew quickly realizes they're not simply facing a natural anomaly, but the trace of an ancient technology, immense, and profoundly alien. A vestige of an era when the galaxy was structured by forces humanity is only beginning to glimpse. At this mission's heart stands Samuel Mercer, a pragmatic officer, lucid, little inclined toward illusions. Marked by past choices and failures he's never truly digested, Mercer tries to maintain balance as the situation escapes all control. But certain discoveries leave no room for retreat. They transform those who approach them. Isolated, deprived of all support, the Niña's crew must face phenomena surpassing human science, hostile life forms, and an even more troubling truth: the universe is not indifferent. It is structured. And some of its structures were never meant to be awakened. The Echoes of the Long Silence is a progressive dive into the unknown, where tension doesn't rest on constant action, but on the accumulation of signs, silences, and anomalies. A contemplative and oppressive science fiction, where exploration becomes confrontation, and where each answer raises an even more disturbing question. This first volume lays the foundations of a series where survival is never guaranteed, where knowledge has a real cost, and where the consequences of a discovery can extend far beyond those who made it.
