Shiver is a beautiful story that is also beautifully written. I greatly enjoyed Stiefvater's writing style and the way in which she portrayed wolves. You can tell when an author has true knowledge of wolves and when they do not, Stiefvater knows wolves. Both main characters, Sam and Grace, were extremely likeable and their story was genuinely touching. The ending was wonderful and perfectly, if not agonizingly, done. Stiefvater left me wanting more and luckily there is more to be had!
