Finally... the story alluded to in the introduction to every book in the other disney fairy series. The plot was very dramatic in a way that works here, although perhaps too much time was spent on the lead up to the titular quest. The character work is what really shines here, I liked the look into Vidia's thoughts especially. I also liked how the changes in perspective were utilized. I didn't enjoy the worldbuilding as much, but it was still interesting to see how it influenced future book.
