Well, first things first, when you look at the cover of the book you see a vampire dashing through the streets of a town. That is not what this book is about.
This book is more about a guy who meets a few other people and travels the world with them, with some tension and aggression here and there, but ultimately without much action happening. That is except the big final battle with the main bad guy, who I guess, no one else could stop, except our main hero who this book is about.
Now, the book is pretty fun and interesting, but ultimately kinda not as expected. There are much cooler things to do with vampires, but here they were just a generic thing to smash in the end without much of a personality.
The book is finished though, things make sense and the setups are paid off.
