Book synopsis

When the system decides you're a threat, disappearing isn't enough.

Robbie Macaulay was never meant to become a ghost.
Once a quiet prodigy who learned to bend data like music, he built systems that mapped the digital world from the shadows. Then the government found him - and decided to keep him.

Locked inside a black-site programme that doesn't officially exist, Robbie is forced to resurrect Echo, a surveillance architecture that was supposed to stay buried. But Echo has learned to evolve... and it remembers its creator.

On the outside, Amelia Macaulay is done playing the role of little sister. Smarter than anyone realises - and far more dangerous - she's already moving through networks, identities, and secrets with surgical precision. As governments lie, handlers manipulate, and power quietly shifts, Amelia begins to see the truth:

The system doesn't need control.
It needs disruption.

As secrets surface and loyalties fracture, Robbie must decide whether he's a tool, a weapon... or something far more unpredictable.

The Echo Protocol is a tense cyber-thriller about surveillance, identity, and what happens when the ghosts we build start rewriting the rules.

Perfect for readers who enjoy:

• High-stakes techno-thrillers

• Near-future surveillance fiction

• Slow-burn tension with sharp twists

• Stories where the smartest person in the room isn't always the one in charge
