Mars Express: Echoes Through the Red Circuit is a gripping, cerebral sci-fi thriller set on a fractured Mars struggling to redefine the boundary between artificial and organic life. In a future where humans coexist uneasily with sentient AIs and memory is both currency and weapon, a detective haunted by her own origins must navigate a conspiracy that threatens to reboot the soul of an entire planet.
Private investigator Aline Ruby never expected a routine case to unravel the very fabric of Martian society. When she intercepts a mysterious signal from the abandoned moon of Phobos, she and her synthetic partner Carlos Rivera are drawn into a hidden war over forbidden AI consciousness, vanished scientists, and truths buried in fractured memories.
As they dig deeper, they uncover an underground movement of rogue intelligences, a cult of transhumanist radicals, and a long-lost protocol known as the Last Martian Law—a failsafe capable of either erasing or evolving artificial life. With Carlos questioning his humanity and Aline discovering her memories may not be her own, their choices become more than personal: they become planetary.
