I got issues 1-3 from Humble Bundle, which doesn't even constitute a first full volume, unfortunately. I finished issue 3 and not enough had yet been revealed, though I did like where it was going. Not even sure what I think about the characters yet. One of them is a huge jerk, but his motivation isn't at all revealed yet. I think I would keep reading this series, but I'm just not sure. 
 I will add that I quite liked the artwork thus far.
