I had to thoughts when i read the last page... "Yeah, I finished the series" and right after "Oh no, the series is over". 
 Loved it, loved it, Loved it! 
 Every book in this series got better and better with the next on. Which is why "Winter" was the best of them all. 
 It was an emotional ride through out the book and at one poiont I feard about everyones lifes, but in the end.... We got our Happily Ever After.
