I thoroughly enjoyed Daughter of the Moon Goddess, but I did not enjoy the second book as much. I found it difficult to get into and the plot a bit frustrating - it seemed predictable and a bit slow and the love triangle less intriguing than previously. That being said, I do still love and highly recommend the duology. The writing is beautiful and descriptive, and the celestial kingdom is imaginative - I would love to explore it with Xingyin. I just would have preferred the first as a standalone.
