If my best friend was telling me this story I would be enthralled and loving every second of it.  However, it reads at best as good fanfic/AO3, which if it was a friends would be heavily invested in. As I’m not it was enjoyable but lacking. Great for a quick fun read but nothing that’s going to keep you obsessed until the next one
The time line was probably one of the better ones for a fantasy novel. Problems weren’t quick fixes and required effort. 
Points for preface and glossary.
The new world/culture and creatures was wonderful but surface level. Gave Avatar (Cameron) vibes. Where it’s bright and shiny but not complex.  moderate attention was given to environment and creatures. politics, religion, and society was rather brushed off. 
Characters were two dimensional without character development to go with angst, exception to the main character. Avery was sweet and kind and brave but naive at best and cringy at other times. Every other character was in her world as plot points without substance. 
A very pro America novel. That survived a world changing event unscathed and in a typical manner.
