Book review: Shiver by Maggie Stiefvater

I finished reading Shiver by Maggie Stiefvater today, and I think it deserves a review just because of how good it was.  
*Spoilers*

Shiver is about Grace and Sam. Grace was attacked by a pack of wolves when she was younger and only survived because of a yellow eyed wolf protected her. Since then she has watched the woods for the yellow eyed wolf to appear. Every winter her yellow eyed wolf makes his appearance and every summer he disappears.

Sam is the yellow eyed wolf Grace watches for. He is a wolf during the winter because the cold changes him into a wolf, and a human during the summer because the heat changes him to a human.
 Grace and Sam connect in ways they have not connected with others before. They also feel deeply for the other in a powerful way. As the winter draws closer Sam must fight to stay human, to stay with Grace. Grace doesn't want Sam to change back into a wolf because it could be his last change.
  The relationship between Grace and Sam unfolds as they explore communication between touch, taste and speech. Their time is limited however as winter draws closer bringing with it colder weather. Sam has little time left in his human body before reverts back to his wolf form.
   Shiver is written beautifully by Maggie Stiefvater. She describes things in vivid detail and describes emotions in such a powerful way that the reader actually goes through the pain or hurt the character is feeling. Some parts of the book actually brought un-shed tears to my eyes which wouldn't have happened if the writing wasn't so well done.
 I couldn't decide whether to read the book or not at first because some of the recent reviews of the book had rated the book rather poorly, and also the book is aimed at teens and sometimes the teen books can be quite young. I'm glad I ignored my doubts though and went ahead to read it anyway. I did find the book dragged in the middle during the summery happy days, but winter soon made it's appearance, bringing with it danger for the book's young couple.
I would highly recommend the book for anyone who enjoys the 'Paranormal Romance' genre.
