I will say, this was an easy, smooth read. There aren't any paragraphs that just run up the length of the book (which I've seen much too often). The story definitely pulled me in within the first few chapters, butt out did get a bit dull after that. It took a while for things to get interesting again, but once things picked up, it got much better the further into the story I got.
One thing I do want to point out is how odd reading Aderes's backstory felt. I can't really describe it, but reading what happened to her didn't seem to flow naturally. Maybe it was too detailed? Other parts of the book suffer from this as well. I've realized that there is a such thing as going into too much detail.
The human character's hate and fear of the "creatures" definitely came across as believable. I don't know why they were so hesitant to call them what they were: Dahmsheds, basically vampires. There are also other creatures that are known by other names than the ones used in this book, but I find new takes on mythological creatures interesting, so I don't mind the changes.
As for the characters, initially, Jason annoyed the hell out of me. However, I'm not sure his behavior would be any different from any other human in his situation. Knowing that did little to help me connect with him, and that's a no-go since he was supposed to be the relatable guy. I came to respect him a bit more later in the story though.
Aderes on the other hand, was an interesting character from the get go. Her backstory, however stilted the delivery, was a gripping one, and it explained why she acted the way she did throughout the story. Also, she is an awesome character overall. I enjoyed her POV more than any of the other characters.
Speaking of POV, I feel the different POVs could have been handled better if this was written in 3rd person rather than 1st...though I suppose it did allow for a more intimate look into the various characters' heads. The descriptions of the characters seemed a bit unnatural as well, like the characteristics were just being listed off. Though, I suppose describing physical traits is a straightforward process.
Personal note: This book had way too much winking. I can't help but cringe and get creeped out when people wink, and it happens so much in this book. Definitely could have done without that.
All in all, the book was ok. It wasn't mind-blowing nor was it awful. It was a decent story with a few...well one or two really interesting characters, and premise that was like many others (Though the execution could have been better). I'll be checking out the next book, because hello, more Aderes is something I'm down for.
