This book was pretty good. I will start by saying that I did not read the first book. I found this as a free ebook, not knowing it was a series, and gave it a shot. After reading it, it was almost like I didn't have to read the first one, because so much of the text was dedicated to recap of the first one. This got really repetitive and was not necessary to understand the story.
The writing was pretty good. Very descriptive (maybe a little too descriptive at times). I think it got a little too detailed as the book went on, especially once the narration split between following Issy and following Dex. The narrator often repeated what each person was feeling and it really wasn't necessary.
My big critique of this book was that OH MY GOODNESS THESE CHARACTERS ARE SO DENSE! The narrator pretty much gave all of the plot twists away in the beginning by giving too much detail. And the characters couldn't figure it out until the end. So the reader is stuck knowing what is going on while the characters bop around, following dead end after dead end. Not only that, but when they finally figure it out, the narrator gave to a recap of the whole situation, detailing events that the reader was able to pick up on from the start. The writing was overly simplistic and a little insulting to the reader.
Despite this, it was still an interesting read. I liked the whole demon aspect of it. I'll admit that I'm not a huge fan of romance stuff, but I was able to speed-read through those sections to get back to the main story.
A quick and simple read for when you don't want to think too much.
