I just finished reading "Z is for Zombie" and am still reeling, and a bit in awe of the journey that was this story. There are 16 chapters to this story and the end of each one will leave you anxious to get immediately into the next one.
This is a post apocalyptic story that features zombies, and one zombie in particular has the main antagonist role throughout most of the story. However, the story is about much, much more than just the zombie, or the end of the world, for that matter. The story is set around a group of 8 kids and one non-communicative adult who try to make sense of, and survive in a world after 'The Changes.' In addition to the obvious challenge of survival in a now hostile world, the kids have to figure out how to relate to one another and build a life together in such a way that will give them security, but also love and happiness, too. The story is all about their journey toward that great end.
Geron did an amazing job creating a world that, despite its hazards and hardships, I wouldn't mind visiting and even spending some time exploring. I loved this story, and if you give it a chance, you will too.
