I just finished Kay Kenyon's Bright of the Sky. I'm currently crafting a review but I don't feel like I can define my enjoyment of the book until I read the subsequent volumes. While some serial books can be read purely as independent volumes, this is not one of those books.
So my question for you is:
When reviewing books that don't have enough individual plot resolution to be considered stand-alone, what are the most important elements to consider in your review?
