If you've not read the six previous volumes of this comic series, this will be a bit of a mystery to the reader. It's a very good series which had improved as it goes along, dealing with a phenomenon where various dead people are “revived” to live amongst the locals in a small US town. The characters are well-developed and sometimes it is hard to keep track of who they all are, especially if there's a sizeable gap between volumes being published.
It is clearly-illustrated and this volume has plenty of gore and blood. It's a series which I recommend and hopefully there will be one more volume – and one only.
