When eight-year-old girl, Jie, sees an enormous lightning dragon hovering over her hospital bed, her first thought is to wonder what on earth the nurses put in her IV this time. But the dragon turns out to be terrifyingly real... as does the deal he offers.

Should she swear a blood pact under penalty of death, the dragon, Ming, promises to restore her health and provide her with revenge against those who crippled her and murdered her beloved family in front of her.

But in exchange, Jie must travel to a mystical, savage world where the strong take what they wish and the weak suffer and die. There, she must grow powerful enough to do battle with the followers of Fang Zhuyu, brutally unstoppable individuals capable of slaughtering entire armies of gods singlehandedly.

It will be up to her to save her new world and countless others from the nightmare of the ancient evil they wish to unleash.
