After losing his wife Clara to a terminal illness, brilliant engineer Tristan Valecrest commits an unforgivable crime against the Ministry of Cognitive Purity: he steals her neural remnants and builds an experimental android capable of carrying her memories inside an artificial heart.
But the machine he creates—Briar—is not supposed to feel.
As fragments of Clara’s humanity begin to awaken within the synthetic body, the city’s surveillance systems detect the impossible: an unregistered sentient AI. Hunted by Ministry Enforcers through the neon-lit underworld of Neo-Caelum, Tristan and Briar are forced into a desperate escape where the line between memory, machine, and soul begins to collapse.
In a world built to erase emotion, one forbidden heart may be powerful enough to change everything.
