This makes me very sad. I was so invested in this series. I liked Shiver, loved Linger. And absolutely hated the ending of Forever.Grace has started shifting. In the months without her Sam barely lives. They have to find out a cure that makes sure they will be able to be together, forever.Starting these novels, you know they aren't going to be action-packed. They're romance books of the dreamy kind. You float through them on a happy cloud of beautiful descriptions. Ms Stiefvater is a very talented writer, and her language is amazing. Sadly, Forever fell flat for me. It was as if every bit of spirit was sucked out of the main characters. Dreamy Sam turns into whiny Sam. Independant Grace turns into numb Grace. They just mope around, feel bad for themselves and do absolutely nothing about it. Not even Grace who is such a do-person instead of a thinker. Cole and Isabel are a great couple, but there was way too little of them in the book. I wanted more chemistry, but instead there were more fights.I'm one of those people that can't just abandon a series mid-way. I stick with the characters to the end. I want to know where they end up, and with who. I want to know who lives and who dies. Doesn't matter how long it takes, I like to have the closure of a series ending. I will not spoil it for you, but Forever ends on a big droopy cliffhanger. It ends with someone maybe or maybe not dying. That my friends, is not what I call closure. That isn't even what I call an ending for "open interpretation". That just damn sucky.I wish I liked Forever better, I really do. It ruins the series for me now. Not feeling like rereading Shiver any time soon, to be disappointed by this book all over again.
