Five years after Dr. Ilya Serrin vanished during the Mars event, Earth has moved on-or so it seems. The Martian colony lies abandoned, quarantined by a silent international accord. But across the globe, something is changing. People with no connection to Mars begin to dream in red. Technologies inexplicably malfunction. Memories appear in minds that never lived them.
Enter Cam Reyes, a former linguist turned fringe investigator, who carries fragments of Ilya's memories-memories he should not possess. Plagued by visions of Martian architecture and impossible voices, Cam joins a covert agency investigating "Echo Events"-psychic disturbances linked to the now-deserted outpost.
As Cam and a team of reluctant survivors travel to a buried lab beneath the Nevada desert, they uncover a terrifying reality: the Martian phenomenon was not contained. It has spread. And its next emergence is rooted not in alien biology, but in the very architecture of human thought.
Haunted by echoes of the past, hunted by forces that erase evidence of their own existence, the team must follow a trail of encrypted journals, rogue AIs, and recovered consciousness fragments to reach the source. But Earth itself may already be compromised. What began on Mars was never just about Mars.
Echo Earth deepens the trilogy's psychological and philosophical core-exploring memory as contagion, identity as infrastructure, and the terrifying possibility that Earth is no longer home, but host. The Red Wake continues, and it remembers everything.
