When I believe in my ability to do something, there is no such word as no.

Zombie books were going to be my passion projects, but certainly not pay the bills. I thought I was going to have to get a real job on a sitcom or something, and have my zombie books to remind myself I was still a writer at heart. I never thought I could actually pay my bills and write what I wanted.

I always wanted to know more about these characters, these little plastic figures I played with as a kid.
