|Get your teeth into writing a zombie novel|
This is a big mistake. Too many characters and too many stories distance the reader from the story you are trying to tell. You want to being everybody into the world you've created.
When it’s a genre that people are well acquainted with like zombies, you need to stick to the rules. By all means push the limits. I recently read a book by a well known author who gave one of his zombies the gift of thought. Bad enough, but he also gave them the cloak of invisibility. I threw that book across the room in a hissy fit.
People should know who’s speaking even without speech tags. This is tricky to do.
Simply surviving isn't enough. Just look at The Walking Dead. They always have a goal, whether it's to get revenge, find the rest of the group or help take Eugene to Washington because he says he has a cure.
For instance, in Dead Bastards they had to go to a shopping mall for supplies. There was no way out of it. Having goals creates conflict and brings your characters to life. Put your characters into a situation and see how they get out of it.
In the case of the hit show, they focussed too much on the Lori, Shane and Rick love triangle. In the end, I’m sure I wasn’t the only one who got bored with it. If I wanted that kind of storyline, I'd watch a soap opera.
In a zombie novel, the zombies must be king.
Will it be the shufflers or the runners?
Will they be smarter zombies or the standard slow kind?
Choose wisely, then run (or shuffle) with it.
Remember, it's your story and nobody can tell it like you can:)
