First of all, thank you so much to Sophie Jordan and HarperCollins for this ARC. The book itself is gorgeous with illustrations and sprayed edges. 
But my review here is honest and 100% my own.
I really enjoyed this book. It was the type of romantasy I fall for. Yes, the characters were full of tropes and the plot was a bit cliche and easy to guess the twists, but a plot full of arranged political marriages, folkloric creatures, a war against magic, and a mysterious past is something I will eat up every time. I deeply loved the two main characters, while also deeply hating Gale—oh sorry, I mean, Stig. I wish there was more of the sisters, too.  
The writing itself was beautiful but not over flowery to make it difficult to read. The descriptions and worldbuilding was just immersive enough. 
One thing I wish was that the ending wasn’t so rushed. I think the author could have make the book a little longer—which wouldn’t be unprecedented for fantasy—and taken time to flesh out the plot twists and characters’ reactions to them. 
Still, I am excited to read the sequel when it comes out.
If you like dragons and enemies to lovers type of stuff, this is for you.
