Somewhere in the midst of all that, Fred presented me with the full blown world-building behind my dream, including the basic mechanism of zombification, how and why the Seals work, and who it is that is leading the struggle of the living against the dead. And they're pretty novel, certainly new to me; though like most ideas, I'm sure someone somewhere has done them before. I don't have a plot yet, but if I weren't deep in the somnolent seas of chemo, that would be enough for me to knock out a handy little zombie novella today.
Ok, chemo isn't over, but I am waking up. Maybe I'll write a zombie story next month.
