I'd give this 2.5 stars, I rated it lower because it was still significantly worse than Shiver. 
 This book was so friggin' boring. Nothing happened for most of it. There was a lot of changing perspectives between characters and I had a hard time distinguishing them because they all had the same voice. I would have to put the book down and then come back to it and go, "Huh, why is Cole so fascinated by Sam's sheets...oh this is Grace." I also found Grace and Sam's romance to be tedious and ridiculous. I get it. They're in loooooove. And it's not just a high school romance...it's so much more! But it isn't really. They're incredibly co-dependent and annoying really. Now, I think it's actually a fairly realistic interpretation of such a romance, but it's still annoying. 
 By the end, I did manage to get sucked in enough that I'd like to read Forever. But I have a feeling it's not going to be oh-so-good or anything. I should really try out some different Stiefvater at some point, I've heard her other stuff if a lot better.
