key of z, make sure to pick up the trade paperback when it is released in march. in fact, i strongly suggest that you read all of the issues back-to-back, whether in trade form or in issue form so you can see the gradual growth from zombie comic to revenge plot, it’s handled wonderfully by all parties involved. to make this simple for you, key of z is walking dead meets kill bill, and if that’s not enough to get you to want to read the series, then you’re not invited to birthday party.
