Excellent book. 
 Often when there is a lot of buildup to a couple over several books (in this case 9 books) the book winds up being a letdown. Not so in this case. Nalini Singh has a total winner in Kiss of Snow. 
 The book is a bit slow, I think it wouldn't have seemed as slow if we hadn't been waiting for this story for so long. She took her time revealing them as a couple, letting them get to know each other as a man and a woman, dating, and taking the relationship in slower steps. She also gives us a side story of Walker and Lara that we can also enjoy and a lot of progress in the Psy Counsel/Changeling conflict. 
 This book was so complete, so satisfying, I almost feel like it could be the end of the series. Doors are open, you can see new characters, new story in the making (and there is another book after this). But if you want a period at the end of a sentence, this book could be it. I've felt frustrated with a few of the books, like Singh had lost her way a bit, but this really left me with a satisfied smile on my face. 
 My only complaint in the book is that Nalini Singh has too many "S" names. Sascha, Sienna, both living in Sierra Nevadas. I kept getting confused!
