I liked this, I found it slow going at first but picked up really fast towards the end. There was more swearing in this than I'd like in a YA and it almost turned me off from the book. But after a while I stopped noticing it and started to really get into the story.
I liked the idea behind this, the entity. It was a refreshing change to most origin stories we are used to (Cane, Vlad, etc) and I really thought it was an interesting storyline once we finally are clued into exactly the curse that is presented.
I liked Ari, she's a tougher chick than you find in most YA novels. She's not a damsel in distress or clingy. But the character I really liked the most was Violet. Loved this girl! I'm looking forward to the next novel in the series! It should be a promising one!
