The system is gone.
The world is free.
Harper is alive.
But the silence isn't peace.
A message appears with no sender.
A voice whispers in her mind.
The enemy she destroyed is still inside her.
Now Harper must fight a war no one else can see -
before the system returns and the world becomes a prison again.
A standalone sci-fi thriller with a killer twist and a high-stakes finale.
