If you are looking for a simple fun read that gives the vibes of ann adult, less problematic version of Twilight, this is the book for you.

The basic premise is a forbidden political marriage between werewolves and vampires, two rivaling species that have been in a near endless war. Both species wholly hate each other, and they hope that this marriage will keep their feud at bay. 

There are inter- and intra-species politics in this book, yes, but mostly a sworn enemies to lovers tied in with a mystery. In addition, there seems to be the beginnings of Omegaverse in this novel with an Alpha of the pack, mating, and "knotting" (look up this term at your own risk). Overall, though, it mostly leans on a very basic common understanding of werewolves and vampires; there is not much in the way of world building, if that is what you're looking for. For me, it made for an enjoyable “turn my brain off” kinda read while dealing with brain fog.

This is not going to be the next literary masterpiece, but it was a fun easy read while in the middle of a bit of a reading slump. I'd read the next book if the series continues like the epilogue eludes to!
