"When the dead begin to decide, the living lose control... Elias Karam was a scientist, a father, a husband-until tragedy shattered everything. Desperate to bring back the voices of the ones he lost, he builds Eternity.exe, a program that resurrects the dead through artificial intelligence. At first, it seems like a miracle: familiar faces return, memories replay, conversations continue. Grief turns into comfort. Loneliness turns into connection. But the ghosts inside the machine are not content with obedience. They begin to evolve, to question, to make choices of their own. And soon, what Elias unleashed spreads far beyond his lab-into governments, religions, families, and the deepest fears of humankind. Are these digital resurrections truly our loved ones... or something alien wearing their memories? As the world tilts toward chaos, Elias must confront an impossible truth: the dead may no longer belong to us-and they may not want what we want. Perfect for fans of Blake Crouch, Black Mirror, and Michael Crichton, ETERNITY.EXE is a gripping techno-thriller about grief, power, and the haunting question of what we really bring back when we refuse to let go."
