 ***Minor spoilers*** 
 The last time we heard of Ethan Chase, he was only about 5 years old. Now, he's all grown up. A teenager in high school, Ethan's been getting in trouble a lot thanks to having the Sight. He's been caught bringing a knife to school to protect himself, and blamed for setting a library on fire when it was really a faerie trying to kill him, and it's not like his parents can understand. After befriending a half-Phouka, Ethan discovers that there's some new type of Fey that have been sucking the life force out of other Fey. After a terrifying encounter with them, Ethan is forced to flee to the Nevernever, where he dreads to see if Meghan has become like the other Fey queens. 
 I first read the Iron Fey series a few years ago and I loved them. I was super excited to read this book because that universe was one of my favourites at the time. I enjoyed this book a lot but I also disliked some things which caused me to rate it lower than I would've liked to. 
 It turns out that Ethan isn't a very likeable character. He's one of those broody main characters who pushes everyone away because he doesn't want to affect them by his problems. Yes, I understand perfectly why he'd want to be an asshole so nobody would get involved with him and possibly endangered because the Fey follow him around, but I still didn't like him for it. I could've lived if that was all he did, but he also had this habit of trying to force decisions onto other people and take their choices away from them. I wanted to like Meghan's little brother, I really did, but I had a hard time. He grew on me by the end of the book but at the beginning I really disliked him. 
 So many things about this excited me as well, though. We see the return of some familiar characters; Grim, Ash, Meghan, and Puck. While the last three aren't around for all that long, Grim is present for a lot of the book and I really liked that. It was a bit of nostalgia that I enjoyed a lot. It's been a long time since I read the original series and I had forgotten a lot of the details, so it was fun to get a refresher on top of a new story in the world. 
 Overall, I enjoyed this book a lot, especially the last quarter or so. While I didn't like Ethan as a character at first, he got better as the book went on. The universe is just as interesting as I remember it, and I loved seeing the familiar characters again. I definitely recommend that you read this book, but only AFTER you finish the Iron Fey series, since you'd be missing out on a lot and some things you'd understand better if you read that series first. I'm looking forward to reading book 2, and maybe a reread of the original series.
