The Girl of Fire and Thorns has a beautiful setting too. The desert and hill country almost become a character by themselves as Elisa and her companions traverse their dangerous terrain. I liked how the setting descriptions were based on story action as opposed to heavy sentences full of descriptors and no character movement.
There is a lot of lore surrounding the magical Godstone and I don't believe we have even cracked the surface to its magical properties and how it will shape Elisa's future. I'm excited by this! I love a high fantasy book that peels away in layers. I believe Rae Carson has set us up for just that kind of trilogy!
