I caught up with this series in a few days, and I'm so happy that I gave it a shot.
Pros: lovable and deep characters with ACTUAL human development and emotions, unique story line that includes blood, sex, and super humans known as "tagged", the use of a bad ass disabled main character, art that seems to improve with each new chapter, easy to follow fight scenes
Cons: sometimes confusing story line because of all the mafia families and the characters within them that intermix and mingle that can sometimes confuse the reader as to who is who and who is doing what and why (this is pretty bad because all of the names are english names...), some racist depictions of black people, no regular chapter updates (because the author has an illness that leaves her hospitalized often), sometimes hard to tell what speech bubble belongs to what character, hard to pick up that Nic is deaf (not sure if this is on purpose or not, but he does sometime speak, and when he is signing usually a black speech bubble appears, but sometimes it doesn't so it can be a little confusing)
It looks like there's a lot more cons that pros (oops), but I love this series so much, and I can't wait for future updates.
