We always thought that vampires are just sucking blood creatures but not. They have tried to protect both themselves and others. We humans should also do the same by treating others with respect too. When others are treated with respect they will too in turn respect you.
I completely loved this book! It was funny, interesting, and gave an entirely new twist to vampires in general. Nina is, in my opinion, a good role model, wanting to help others. While it is true that there's more swear words that you might expect, I read this at age twelve without having any problem with it.
