Might I suggest The Host by Stephenie Meyer. Unlike her twilight saga, the host is a science fiction/ romance adult novel. I love this book. I at least suggest that you go and watch the trailer for the host the movie which is coming out this March.
I've actually already seen the trailer for The Host. It looks really good! I've already decided that I'd like to read the book before seeing the movie. I hope I'll like it. I used to love Twilight, but I don't really anymore. Not as much as before.
I read the book right before the movie came out (yay binge reading!) but never went to see the movie because I have heard that everyone who has read the movie hated the movie :/
