3.5 stars. 
 This whole review will contain spoilers. You've been warned. 
 I should preface by saying that I really did love so many parts of this book. It was excellent, though a little slow in some areas. The narrative was well organized, and split fairly evenly among the differing POVs. The plot was engaging and continuously. The dialogue was on point in so many areas. The ending was perfect, and so fitting for each character. I cried the last twenty pages on, on top of the heart attack I was having the last 100 hundred pages. It was just well done. 
 And Winter. What an addition to this cast of characters. She was so beautifully done, and I loved the subtle way Snow White's origin story played into the overall story. Those moments made me fangirl so hard. 
 I have two complaints that lead to the half star reduction. While I really wanted to LOVE the book, I just couldn't get into it in these moments. 
 1. Jacin. I'm just not a fan. This book made me care about Scarlet and Wolf a little more. They were my least favorite pairing going into this book. But I couldn't get into Jacin's character. He's very sweet to Winter, but past that he didn't do anything for me. At times, he was tediously protective. His whole function as a character was just to hover over Winter. It got boring very quickly. 
 2. Winter's ending as a whole. I loved Winter. She's so unique and beautifully flawed. Her madness was wonderfully crafted, and I loved every moment she was featured, even though many of those moments broke my heart. Her madness makes her character, which is why I feel cheated by her ending. In the end, we're presented with a solution for protecting people from Lunar manipulation, and possibly curing Winter's lunar sickness. I understand the need for this plot point, but it made the ending feel too clean, and counter-productive to everything that's made Winter Winter through the book. I don't like the idea that mental illness is something that interferes with a happy ending, like it's an afterthought that needs to be swept under the rug for a character to be happy. Winter's character is beautiful and heartbreaking and so different from most of YA fiction, and while I'm so happy she gets the ending she deserves, I'm a little heartbroken it means an end to Winter as we know her. I'm still very conflicted over it, and probably haven't organized my thoughts well, but it didn't sit well with me. 
 Overall, I loved the ending this provided for the series. It was so well done, and I'm sad to see my babies go.
