FINALLY a title and synopsis! It feels like forever since the last book was published. I can't wait! 
 Update 10/28/15 
 So it feels like I've been waiting for this book for about eighty years now. 
 Sure, I've had the Blood of Eden books to tide me over (and those are excellent) plus her dragon series that I haven't gotten to yet, but there's nothing like reading about my favorite faeries and their human friends. When the release date for this was pushed back to two years instead of one, I was pretty upset. 
 The Iron Fey series is one of my all-time favorites, and it's hard express the depth of my attachment to the characters. They feel like my old friends, and their world feels like home. The fact that I would probably die within two days in the Nevernever is besides the point. This was an excellent conclusion, and for many reasons. 
 (view spoiler)[I'm glad Kierran was only evil because of losing his soul. I was kind of on the fence with his character throughout most of the series but in the beginning he was only trying to save his true love and then it just got out of hand. I'm pretty sure Ash would have done the same thing had it been Meghan who was dying. 
 I wish I had gotten more attached to Ethan and Kenzie. I don't dislike them or anything, but eh. I loved the reappearance of Grimalkin and the Wolf, they were awesome as usual. The saddest part of the book was probably Annwyl's death, I was surprised she actually Faded. I figured there would be some heroic save and she would live happily ever after with Kierran, but I guess not . . . 
 Also: I found it surprising how nice Mab was in this book. Well, maybe "nice" isn't correct, that's never a good adjective for the Winter Queen, but she actually wanted to protect her family and had some decent motivations. How strange. (hide spoiler)] 
 I can't give it a full five stars because I don't feel like it's quite as epic as some previous installments (The Iron Knight is my favorite), but it was still awesome and I'll proudly display these on my bookshelf for years to come. 
 4.5 stars
