When a cryptic message is found carved into the wall of a murdered journalist’s apartment, disgraced intelligence analyst Sera Morgan is pulled back into the world she tried to escape. The message leads to a hidden trail of secrets tied to five keys — each unlocking a layer of a global conspiracy involving powerful elites, forgotten archives, and a deadly AI project that was buried for a reason. As Sera races across cities and through shadows, she must decide whom to trust and how much of herself she’s willing to lose to stop what’s coming. Time is against her — and so is someone who knows her every move.
