After Shiver and Linger, I was sure that this book would make me depressed with its beauty, however that didn't happen. I love Sam and Grace, but I think the best characters in this book are Isabel and Cole. They outshine everyone else in this book. They have a more real relationship and are the ones to bring movement to the story.My problem with this book is probably related to the fact that this is the end and it didn't feel like an ending. I mean, there were some unanswered questions and that's something that drives me crazy. What will happen to Grace when they infect her with menigitis? Will she be cured or will she die? And Sam? and what will happen to the pack? Will Cole's cure be able to bring them back to human form?I feel that while Shiver and Linger were almost poetic, with their beautiful narrative, however Forever appears to be outside the series. It doesn't have the same rythm that I love. It's not that I didn't like it, It's just that I didn't love it like I loved the previous two. =/
