Princess Snow only cared for one thing; being good enough in her mother's eyes, but the key to gaining her mother's favor was always one thing; unlocking her frostblood. In a desperate search to find information about her dormant frostblood, Snow discovered a terrifying secret that her mother has kept hidden for the past fifteen years: the origin of frost. This discovery led Snow to be trapped in a frozen hell, and it didn't take long to learn that she wasn't alone. Nightmarish creatures of darkness are also trapped here, blackblooded monsters capable of consuming frostblooded people and their souls. Luckily, Snow finds an ally: one of her mother's frost veterans, who teaches Snow how to survive this harsh world and explains the imminent threat that can no longer be contained. Snow must endure and ensure these beings do not escape their prison, or the world's fate will be that of darkness.
