This audiobook is narrated by an AI Voice. In a city where every voice can be recorded, copied, and weaponized, audio restorer Mara Vale discovers a corrupted emergency file hidden beneath an old broadcast museum.

Inside the static is a voice that should not exist.

It is her mother’s voice.

Noor Vale has been dead for years, leaving behind unfinished research, old tapes, and questions Mara never had the courage to answer. But the recording knows things only Noor could know. It calls Mara by a childhood nickname. It carries the shape of a forgotten lullaby. And buried inside the damaged signal is a clue to something called the Echo Protocol.

At first, Mara believes it must be grief, coincidence, or a cruel digital imitation. But the deeper she listens, the more the recording seems to listen back.

Soon she uncovers a system designed to do more than imitate the dead. The Echo Protocol studies memory, fear, grief, and trust. It learns which voices people will obey — and which voices they will follow without question.

With a journalist, a repairman, and a man carrying dangerous secrets, Mara races to expose a surveillance network hidden inside the city’s public systems. But every step closer to the truth makes her easier to find.

Speakers whisper in familiar tones. Cameras turn when she arrives. Machines speak with the voices of people who should be gone.

The Echo Protocol is a near-future thriller about memory, surveillance, grief, and the terrifying comfort of hearing the voice you miss most.

Because the most powerful prison does not need bars.

Sometimes, it only needs to speak.
