A Dance with the Dark Fae by Valerie Harmon

You can’t say “no” to the Dark Ones, for there may be serious consequences.
The Dark Ones shouldn’t be contradicted. They don’t accept it, for they are never wrong.
I knew these rules since childhood. I also knew that it was in my best interest not to get involved with them. But I did.
And now I have to stay close to one of the Horos brothers, who belongs to the most powerful family of the Dark Ones in Grassor.
There are two of them, and while the younger one is planning our wedding, the older one is doing everything in his might to prevent it from happening. And I’m trying very hard not to fall in love with him even more than I already have…
First of all, because he’s a Dark One.
And secondly, because I’m about to marry Xanor!
