There is a lot of misdirection and "who can you trust?" "Who should you trust type scenarios. It *does* get better (in terms of story line development) across the next 5 volumes, and I am glad that I read it. Even if the main instigator was totally weird, and I kinda don't understand some of the motivations. Also, it just ends. Which, for this story works well enough. But it does just end.
I do really like the two main protagonists. We see many of the characters grow and change (even Marco, although is development is in all of about 3 chapters). If you are in the mood for something with lots of action, lots of monsters, and lots of blood, then this may be the one for you. I am glad I read it, but I can't see myself really re-reading it.
