Engaging?

What has the author done to engage you the reader in a relationship with the books content?
I must say the author of this book has many surprises in her writings. She is not afraid to completely twist the story into something else. It keeps me engaged very much and it's not your typical love story. You know, " boy likes girl, girl kind of likes boy, he does really sweet things for her, and they fall madly in love and get married." I went to sleep just typing that out. She doesn't take away the romantic parts of the love story but the main characters have a total love hate relationship which I love. This book gives me twisted feelings through the whole thing. I'm glad that two people who have love for each other regardless of their differences can look past it all and "go for the gusto". But I'm looking out for the main character Bella as well. What if one day he can't help his urge and decides to nibble on her. One instant when everything was going fine and great, Edward invited Bella over to his house to throw her a party for her 18th birthday. She's goes to open up her gift and right then in there in front of this whole family of vampires she gets a paper cut. Edwards brother is the newest "vegetarian" so he lets his urge get the best of him and leaps for Bella as Edward tries his best to hold him off. Or what about the time when her best friend Josh turns out to be a werewolf. Another attachment to a harmful animal. These examples from the story are just to show how exciting and almost fearful her writing is that makes everyone fall in love with it. It engages any reader because you will never be bored because the drama just keeps coming.
