Where wild minds come to rest
Why not start a blog about it first, and if you end up writing enough, you could transform it into a book?
I've never completed a work about my MD mainly because it's just so extensive and I have ADD (also I had a horrible time changing the names of real people, fictional characters, and celebrities). But I've finished other novels.
When I was working on it, I decided I wouldn't explain it at all. And honestly, that's best for fiction. Exposition is the poison of good writing. At the least, wait until chapter two before adding exposition, but I try to avoid it altogether since I have a really bad habit of explaining everything. Your reader doesn't need his or her hand held. Just jump in and let the reader's mind go wild with questions that you'll answer when the action happens.
Another format I used was alternating each chapter with what was happening in reality at the time with what was happening in my alternate reality. I liked this format because it was clearer that these were fantasies, again without explaining exactly what it was.
Abber, this is a blog. I meant you could blog on here.
You should open it up by saying that Saurus is but one place you've daydreamed about; there are many others, but Saurus is special to you because you got the idea during the period of time you were daydreaming about Saurus.
Maybe you should give details as you go along. Maybe when you were a child you could talk about the daydreams you had as a child. I'm no editor or publisher, but I think you could talk about it with them.
This sounds awesome Abber! I totally think you should do it; I'm a little older now and I wish I had kept better written records of what I was dreaming (pretty sure I was most imaginatively "fertile" as a teen). Feel like I lost a lot of stories just because I thought I'd always remember them.
Also love the title "Paper Dragons."
