There's nothing more satisfying than cold blooded revenge

In the shadow of the South Tyrolean Alps of 2025, fifteen-year-old Theia is treated as an invisible plague by her narcissistic, power-hungry embassador father, two cruel sisters and a barely tolerable brother who turns a blind eye to the whole chenanigans. Her only solace is a weak-willed mother who loves her in secret, and a strange power: since age ten, she can foresee the future just in time to alter it. But Theia's true escape lies in her dreams of Thaumeya, an ethereal, 9th-century magical realm she is destined to rule. On her fifteenth birthday, the dream becomes an odd reality. Thrust into Thaumeya, she awakens as the Guardian of Fates, possessing the cheat to weave the lifelines of both worlds. To claim her throne and exact absolute, cold-blooded revenge on those who abused her, she must hunt down rare artifacts to level up her core. Navigating both medieval courts and modern political parties.
