About this audiobook
When a pioneering neuroscientist is found dead in a locked laboratory, Detective Mara Vance expects a routine homicide investigation. Instead, she uncovers a secret experiment known as The Echo Protocol, a breakthrough technology capable of copying the human mind. What begins as a murder case quickly evolves into something far more dangerous when Mara learns that the experiment may have already succeeded.
As evidence points toward a duplicate consciousness created from the victim’s own mind, Mara must navigate a maze of science, ethics, and criminal law. If a copied mind commits murder, who is truly guilty? The original scientist, the copy, or the technology itself?
Set in a rain soaked futuristic city filled with hidden laboratories and ambitious researchers, The Echo Protocol blends gripping detective suspense with thought provoking science fiction. The story explores identity, responsibility, and the unsettling possibility that the human mind can be duplicated, stored, and reborn.
