I just have a few more corrections to make on the Evil Harvest manuscript. The main thing is clearing up little inconsistencies. A description you write on page 200 is liable to change by page 400. It's amazing the things you overlook in the heat of writing, and even in an edit. I suppose it's never possible to distance yourself 100% from the work. That's where editors and copyeditors come in. For the most part, I think they help make an author's work stronger.
For aspiring writers (turn back, you fools!), I recommend making maps, time lines, even a rough calendar of events in your story. This is especially helpful when dealing with multiple characters and plot lines. Stephen King may be able to wing it and produce brilliant work, but let's face it, none of us are him. Preparation will make for an easier time down the line. Embrace it.
