Serpentine Books in Order

The Serpentine books are fantasy stories set in the Kingdom of Xia, a world shaped by Chinese folklore, demons, monasteries, and old bargains between the mortal realm and the underworld. At the center is Skybright, a young handmaid who has grown up beside Zhen Ni, the daughter of a wealthy household. Their difference in social position is real, but their bond feels much closer to sisterhood.

Skybright's life changes when she discovers that she transforms at night. She is not fully human, and the truth of her serpent-demon nature forces her to question everything she thought she knew about her past. She fears what people will see when they look at her, while also trying to understand what her new abilities might mean.

Secrets do not stay hidden for long.

In Serpentine, Skybright's personal awakening is tied to a larger threat. A breach between worlds puts humans at risk, and demons are no longer safely contained. Skybright becomes involved with Kai Sen, a monk in training, and Stone, an immortal whose motives and methods are not always easy to trust. The story balances supernatural danger with quieter tensions about friendship, desire, class, and belonging.

Zhen Ni is just as important to the series as the magical conflict. Her relationship with Skybright is tested by the changes neither of them expected, but their loyalty remains one of the books' emotional anchors. The series treats their friendship as something active and demanding, not a side note to romance or adventure.

In Sacrifice, the stakes expand as Skybright must reckon with her power and her connection to Stone. The struggle to protect the mortal world continues, while Skybright, Zhen Ni, and Kai Sen face hard choices about love, trust, and what they are willing to give up for one another. The danger grows darker, but the focus stays with the characters and the relationships that keep pulling them back together.

This is a good fit for readers who want a coming-of-age fantasy with demons, shape-shifting, romance, and a strong female friendship at its core. Start with Serpentine, then read Sacrifice to follow Skybright's story through its next, more complicated stage.
