From the premise, I knew this was a fantasy, but it didn't really truly feel like a fantasy until the last fourth of the book. Yes, you have the magical letters and everything, but most of the stories about the gods and goddesses you're just getting from the letters and not really seeing them actually play out until the very end of the book. This does mean the second book has a lot of potential, though!

For much of this book, it reads more like a historical fiction than anything else, something set during WWI or WWII. Thus, if you enjoy historical fiction with more and more fantasy as the story goes on, this book is definitely for you!

The premise of this was fascinating, and I did love the way the letters played out between Iris and Roman. They had really great chemistry from the beginning, honestly. Did their relationship move a little quickly there towards the end? Yes, but also its war, so it made sense in the context.

All in all, I do think I'm invested enough to read the sequel when it comes out next year!
