Twilight

I think the whole concept of a vampire falling in love with a human to be really cool. I love vampire stories to begin with (that is if a vampire is a good guy, aka Blade, Moonlight etc...), so it wasn't too hard to convince me to read the book. I think this is an well written book that is an excellent balance of action and romance and will keep a wide range of people interested in it. Enough action to keep male readers interested and not too much romance that would turn them off to the book.
Down to the details. I really like Edward and Bella's relationship. But I do believe that if she becomes a vampire the relationship will change enough to no longer be interesting (to the reader). It's like her humanity brings out the deep buried human instincts in him. I also think that her "changing" is not a good idea, at lest until she is in her 20's. I know she worries about appearing the same age as Edward, but I believe that he could easily pass for a early 20's college student, and they would still appear about the same age. But I don't think that she will be changed, mainly because the chemistry/tension would no longer be there and not many people would want to read the books anymore. I also think they are not at a stage in their relationship that she should make such a permanent decision. You know teenagers these days, always rushing into things!!
What I can't believe is that she when she was in Arizona (when James is chasing her) she deliberately ditched her protectors to go "save her mom" from the James. How stupid! Did she honestly think she could take out a vampire by herself. But I'm glad that all the Cullens came to her rescue instead of just Edward. It just seems more realistic, to me at least.
In summary, I enjoyed the book immensely. I couldn't put it down. I would recommend this book to everyone I know. It's also a book that I would read over and over again.
