As a girl, I felt that I need to defend myself here.
Yes, I've read all books. For me, the writing style is poor [comparing it to Nicholas Sparks or even Mitch Albom, but then again it is a porn/romance book]. Every five pages, at the very least, contains any tiny bit about sex. If you are inexperienced, you better not read it so that you won't be "corrupted".
I just liked to know what will happen next [maybe I was just a little bored then] but after that, I can't even recommend or talk about this book. I felt that it should be private, like it's an intimate secret your bestfriend of thousand of years has entrusted you.
