 I liked it. The second book in a series is usually difficult to get through because usually it's a bridge book between the first and the last (in a three book series). I am definitely ready for the next book to see how things get resolved. I liked how Ms. Stiefvater didn't go for the love triangle (as unfortunately is the trend right now) when she introduced Cole. To me, it would've cheapend the relationahip building between between Sam and Grace. The overall story was clever. I never would have thought that Grace's not changing would make her sick in the long run. I'm anxious to see how that problem is solved because eventually it will start to effect Sam as well. 
 I was really frustrated by her parents. True, it would be a shock to find your daughter's boyfriend living in her room, sleeping in her bed, for months. But the other point, why didn't they notice before. It doesn't seem as though Sam and Grace were being the most discreet, and they didn't have to. We, as readers, were repeatedly shown how much Grace's parents weren't home. I can understand they would want him out of the house, but to completey disregard Grace's feelings and write him off as a bad person was not reasonable. If you could see how much this boy matters to your daughter wouldn't you try to give him the benefit of the doubt? I hate the whole "you can't know what love is, you're too young" mentality that her parent's portray. 
 As the story was going along I thought that it would be a sad ending, and in a way it was, but honestly I felt more optimistic about it than anything else. Grace can still turn into a human. And Sam vowing to find her and a cure was very upliftin. I really feel as though he will succeed and we will see a happy ending to the series.
