I enjoyed this a bit more than the first book. Some interesting story substance and a few more unexpected twists. I still do not like any of the characters. Although the MC was more tolerable in this one. 
 We get to meet Zom Heads. Not quite mindless zombie but still undead. And in the hands of scientists and some sort of military. So much is unexplained still in this series. WE get some answers but we are as in the dark to the happenings as the MC. It both drew me in and frustrated me. 
 The green moss that is on the zombies is still gross but even worse than that is a new crazy that enters the scene toward the end. Ugh-a combo of some's worst nightmares. I shall say no more. 
 The art was less engaging in this one. Some scenes were boring, others didn't do the description justice. Still it hooked me enough to help make up for the first book and has me wanting to continue.
