putting together a book

I've been spending my day putting together my book - getting it all formatted correctly for the printers. Ran into an unexpected snag when I realized that I don't have 100 pages of text. I figured I would, but I'm about 30 pages short. And I'd like 100 pages... So I have 2 unfinished stories that I'm revising and considering. The beauty is, I'm also thinking of putting in an excerpt from my novel. That would be pretty cool...
