Meh. I'm not overly impressed. Moning's writing simply is not as sharp here as it was in the Fever series. Noticed several factual errors; ie, Max mentioning her blue eyes. Sometimes a chapter with Mac talking ends, and the way she starts the next felt disjointed. Maybe we are supposed to notice. Maybe it's a set-up. But as it wasn't resolved in this book, it felt sloppy. 
 Did not care for Dani's story in this one, either. That's not character development. It's not so much who Dani became that bothers me, it's how it was done, with no glimpses from Dani on how she became this way. Any real insight into Dani came from other characters, and we got nothing from the actual character in question. It felt cheap, and Jada is freaking boring as hell to read. 
 My two cents on the book. A bit lack luster, although I enjoyed getting a dose of Barron's personality again. Also loved seeing more into Ryodan's character. I'm just a firm believer that each book in a series should stand on its on, and this one is a bridge, nothing more.
