Chapter 4 is now available:
I'll try to release Chapter 5 tomorrow and then have the book up on Amazon Monday (1/14/13).
Currently proofreading after a celabratory BBQ feast (pulled pork, sliced beef, chicken quarters, ribs and sweet potatoes). On page 50 of 140. The book ended up being 29,000 words. If it is received well, I'll make this a regular series. I could take this story a long way; lots to explore in a zombie apocalypse.
