What if your identity was never yours? In Signal City, identity is no longer something people discover. It is something they choose. The Identity Market allows citizens to select who they want to be — Builders, Guardians, Dissenters, Strategists — tribes designed by powerful algorithms that promise belonging, purpose, and power. But every identity comes with enemies. As tribes grow stronger, debates become wars, loyalty becomes currency, and the city begins to divide into competing realities. Aren once believed the system only controlled attention. Now he sees something far more dangerous. The system is not guiding people. It is predicting them. And when identity becomes a marketplace, the most dangerous person in the city is the one who refuses to buy. The Identity Market is Book VII of The Attention War series — a gripping cyberpunk novel exploring social media tribes, algorithmic power, and the invisible systems shaping the future of human identity.
