Wow, just amazing! At first, I wasn't sure about it because the sci-fi part is hard to grasp, but don't worry, after the first 80 pages or so you won't be able to stop reading (it has about 600 pages). It has to be the strangest book I've read, but also the best. It definitely ties in with Twilight, and the only reason I don't think it beat it is because Twilight sucked me in for a longer period of time.Meyer is an amazing author who is able to pull you into the story and allow you to feel like you're actually there, experiencing what they experience and feeling what they feel. She paints a striking picture of the characters and the sinister world that they now live in, in the mind of everyone who is fortunate enough to be touched by it. The story is a real page turner. It's so freaky how their world is changed and what they have to do to survive. It's also incredibly unique and touching. I instantly fell in love with this book.The characters in the story were very likable and I found them a lot more realistic than the ones in Twilight. The story was more adult and had a lot more depth to it. It's original, exciting, scary, romantic, and thought-provoking. Stephenie really proved that she has more than one story to tell. If you loved Twilight, and especially if you're a bit older - you will absolutely love this book.
