The premise of this story is pretty dope: a physics professor turned powerful vampire, seeks revenge for his murdered woman. (FYI - some people murdered the shit out of her.) I am here for all of it.
Unfortunately, there really isn't a direct path to vengeance. I'm okay with that (not really), since there wouldn't be much of a story. He has to understand his powers, accomplish certain tasks, meet people, excetera, excetera. Along the way, he makes stupid choices, and brushes them off with the excuse of being “curious.”
But what really irked me during his epic journey, is when he finally comes face to face with the lead antagonist, but doesn't want to kill him. (Even prior to this point, he whines about it. He goes on and on, page after page after fucking page, bemoaning about why he doesn't want to kill someone - as he calls it - "in cold blood.") Even though his nemesis had sent people to kill the person he loved, the vampire's logic is: “well, since he didn't do it HIMSELF, killing him makes me feel bad." Well, if this were literary fiction or a thriller I was reading, then sure, a character's angst over revenge killing is logical. But this is SFF, and dude is a powerful vampire. Git ta vampirin'.
This refusal comes back to bite him on the ass, of course, and it made me want to throw my tablet across the room. Fortunately, I didn't, because I needed to download Book 2.
