Review: Shiver by Maggie Stiefvater

Warning, this is a werewolf book so all of you vampire people can just stop reading here. I am not one that usually likes vampire and werewolf books, but I have read another of Maggie Stiefvater's books and decided to give it a try. Boy was I excited when I finished this books. Here's what Goodreads has to say about it:

"For years, Grace has watched the wolves in the woods behind her house. One yellow-eyed wolf—her wolf—is a chilling presence she can't seem to live without.

Meanwhile, Sam has lived two lives: In winter, the frozen woods, the protection of the pack, and the silent company of a fearless girl. In summer, a few precious months of being human… until the cold makes him shift back again.

Now, Grace meets a yellow-eyed boy whose familiarity takes her breath away. It's her wolf. It has to be. But as winter nears, Sam must fight to stay human—or risk losing himself, and Grace, forever."

I was mainly intrigued by this book because of the scientific aspect. The werewolves in Mercy Falls (pause for cheesy name) change human in the warm weather of spring and then back into werewolves for the winter. The kicker is that they only change a certain number of times before they are  wolves forever. 
Grace is also a very interesting character, her parents basically ignore her so she takes care of everything in the house, all of the shopping, while still going to school. Her life changes when she finds a boy on her deck with eyes the same color as her wolf. He also just happens to be shot, mayhem insues.
Overall, I really loved this book and I am looking forward to reading the rest of the series (Wolves of Mercy Falls).
