This review assumes you've read the rest of the series. I will try my hardest to keep spoilers out of this review. Biting Cold picks up right where Drink Deep leaves off. Merit and Ethan are off looking for a newly escaped Mallory and the Maleficium. 
 I will say that the book was kind of not what I was expecting. Based on the back of the book blurb, I had figured the whole book would be dealing with Mallory and would be away from Chicago. Don't get me wrong, Mallory's situation is something that will be ongoing for a while, but there's other conflicts that have been brewing that are addresses here. Mainly, issues with the GP and mainly Seth Tate. Yes, we finally get answers regarding Seth Tate. It was a little what I was expecting, but Chloe Neill put enough of a twist on it that it wasn't completely what I was expecting. 
 I've read a lot of reviews saying that they wished there was more of this character or that character or this or that group of supes. I know that everyone has their favorites and everyone wants to know what it going on with all of our characters since Drink Deep. I thought that Chloe Neill did a good job of updating on everyone in the series even if they didn't get a lot of page time. Everyone at least had a little presence. I think it's a testament to the world Neill has created that people are disappointed if their favorites aren't in it enough. There's a lot going on in this book. It's a culmination of things that started in Hard Bitten and it's still Merit's story and narration and the other characters revolve around that storyline in how it fits with Merit. I was happy to see all the characters again and I look forward to where they all go in the future. 
 The past couple of books (at least) have taken an emotional toll on our characters. I could really feel it in this book. I felt there was a slight lack of snark and humor that usually litters the pages of the series. I don't think this makes the book bad, I just think it really speaks and goes hand-in-hand with what everyone's been through. Not to say there isn't any humor, but the usual comedic scenes between Mallory and Merit aren't there obviously because Mallory is going through a lot. 
 I know everyone is wondering about Merit and Ethan. Throughout the series their relationship has been a roller coaster. I know a lot of people were devasted by the event in Hard Bitten. I know even more people were delighted by the ending or Drink Deep. I just don't think many people, me included, thought about the ramifications with Ethan's return. I didn't see that there would be things to work through upon his returning. I mean he died, what was / should have been a very final ending. Then to come back from that, back to the living, there will be issues especially in the manner in which he was brought back. But I think that readers need to have faith that since they've already been through so much and put up with so much they are not just going to suddenly throw in the towel and give up. That would feel like a waste and I don't think Chloe Neill would make the readers waste 6 books. 
 Like the previous books, Biting Cold answers a lot of questions. Questions that have been lingering for quite awhile. In my opinion it doesn't really raise more questions as much as it puts our characters on a new / different path that will have to be dealt with in the upcoming books. I guess the one question the ending of this book can raise it what now? What happens now? Luckily we only have until February until House Rules is released. 
 This series remains one of my favorites and I really look forward to seeing where the rest of the series will take us and how things progress from here. Until Then!
