This audiobook is narrated by an AI Voice. In a pristine, pressurized silence, Dr. Evelyn Allen stands on the precipice of discovery, her life's work, the enigmatic Keystone, humming with barely contained power. Her ambition, a quest to find loopholes in the fabric of reality, has led her to the brink of the unimaginable, a place where theoretical physics bleeds into the realm of the impossible. When an unforeseen anomaly manifests during a crucial experiment, it catapults Evelyn not into the theoretical void she sought, but into a desperate struggle for survival in a world stripped bare of its own laws. Stranded in a land of perpetual twilight, hunted by creatures of shadow and despair, she finds an unlikely and deeply distrustful ally in Gideon Steele, the last Sentinel of a dying world, a warrior bound by ancient traditions and a profound grief. Together, they embark on a perilous journey toward a glimmer of hope—a mythical city of light, a dying seer, and a desperate gambit that might just offer a chance to rewrite the very fabric of existence, or to unravel it completely.
