I heard a review about this somewhere, which was along the lines of "if you like enemies to lovers, this book delivers" - and I think that's exactly right. I've definitely read worse enemies to lovers: this was well-paced and I got in a really nice flow when reading; I also liked the world building a lot. Extra points for being a standalone novel (the others in the series share the world, but not the characters, I think). 

The writing flows really well, I read this in a day (it was a day off, but still), and 

Tropes: forced marriage, enemies to lovers, forced bed-sharing, broody MMC
Spice level: 1.5/5 (nice build ups but ultimately fade to blacks...)
