It is a pretty large undertaking, but it's a manageable one. I don't need to be an expert in every one of these fields (or any of them, for that matter). I just need to break it down into manageable chunks.
I expect the book will be somewhere around 70,000-100,000 words when it's all said and done. I know that seems like a lot, but it's really not that bad. The hardest part of any good writing project is the planning, research, and later revision.
I have a post here about my first steps, and although I plan on keeping this community up-to-date, most of my book updates will likely show up on lostmegabites.com.
