City of TartariaSome cities vanish. Others are withdrawn.Beyond the reach of modern maps and forgotten by official history, the City of Tartaria endures-hidden not by force, but by consent.When a small group of children from different parts of the world are drawn into Tartaria, they discover a civilization unlike anything humanity remembers. Tartaria is not a utopia, nor a relic of the past. It is a living system-one built on balance, restraint, and consequence. Its skies behave differently. Its architecture responds to pressure and truth. Its families are chosen, not born into power.But Tartaria is not untouched by the outside world.A near-fit outsider-resentful, brilliant, and deeply wounded-begins to circle the city's edges. Once shown kindness by someone who belonged there, he now believes Tartaria stole something from him. What begins as obsession hardens into ideology. What begins as curiosity becomes intrusion.As the children learn Tartaria's rhythms-its Ocean domain of patience, its Sky of foresight, and its Sub-Terranium of consequence-they also begin to sense something tightening. Rules are being tested. Trust is being strained. And the city that has survived centuries of withdrawal may be facing a threat it was never designed to confront: someone who wants in, not to belong-but to take.City of Tartaria is the opening movement of a larger saga-an unfinished chronicle of a hidden world, its people, and the fragile line between invitation and invasion.This book does not promise answers yet.It promises discovery.
