She built a new reality to escape her own. But she never planned on becoming its savior.

In 2057, immersive technology is the new reality, and for brilliant programmer Ada Lynx, it's the culmination of a decade-long obsession. After sinking her life savings and countless sleepless nights into creating Kremøtoa, her ideal fantasy world, she finally activates the system. But the lines between creator and creation blur catastrophically when Ada's consciousness is permanently uploaded, trapping her within her own creation.

Now an Admin with gød-like powers in a world more beautiful and dangerous than she ever imagined, Ada discovers her digital utopia is deeply flawed. A mysterious digital corruption is decaying the world from within, while the tyrannical Ehxcehl Empire sees her abilities not as a miracle, but as a threat to be controlled or destroyed.

Hunted by the Empire's ruthless Prefect, Kraus Valerius, Ada must forge a new path. She finds herself in a precarious alliance with Seraphina, a decorated Knight-Commander questioning her own rigid loyalties, and Korina, an exiled scholar whose insatiable curiosity is matched only by her brilliance. Together, they are joined by Erita, a cynical spymaster with a hidden heart and a grizzled sea captain with unwavering loyalty, forming the core of a fledgling revolution.

To survive, Ada must embrace her role as a reluctant visionary, debugging a world teetering on the brink of collapse. As she navigates treacherous political landscapes and confronts threats that rewrite the very rules of her reality, she discovers her greatest challenge may not be saving the world she built, but navigating the unexpected complexities of her own heart as her bond with her companions deepens into a love her code could never have predicted.
