Query: This is great!!! Really the best!!!

I think this is the best book out of the 4-book series. I couldn't stop reading it and you HAVE to read it if you're one of those romantic-thriller types. It's the story of Elena turning into a vampire and finding out who this "Other Power" is. If you seriously want to know, then seriously read the book. Don't ever read it at the evening. You'll just be up all night trying to read the whole book. I did. :o
