This is a total different form of fantasy than what I usually read and I enjoyed it. There was a lot that happened in this book, and the thing that I found most interesting was that it had a little bit of history etched into the story, of course there were a few things that were tweaked to make it into a fantasy fiction novel. On the author's page: "around the invasion of Persia by Alexander the Great" 
 We get introduced to supernatural beings like wights, other demon-like beings, and some beings like Revenants but with a twist (Necromancy) were introduced in The Midnight Sea. The daeva, where the more human of them, and could be bonded to a human, a Water Dog, to control and fight together against the evil Druj. The story centers around Nazafareen and Darius, her bonded Daeva, and at first I didn't know what to think of the story, because it was so slow and confusing at first, but then the more I read, the more complex it stated to become and I was hooked. 
 Basically I feel like whatever I say won't do the story justice. Just suffice to say that I'm eagerly waiting to read the next two books in the series.
