When a forgotten jungle near Mexico City reveals a city that shouldn’t exist, Jessica and her team are drawn into a mystery that defies maps—and memory. What begins as an investigation into a ghost town with no past spirals into a global hunt for the truth behind Vanguard’s resurrection and Jessica’s origin.

From shadowed alleys in Paris to the remnants of Cold War-era labs in Eastern Europe, Jessica must confront the possibility that she was never the original—only a copy of a memory that refuses to die. As the lines between past and present blur, she faces the most dangerous question of all: If she was never real to begin with, can she still choose who she becomes?

Some echoes are too loud to silence. And some memories refuse to fade.
