Someone on the Kindle Boards put me on to this site where you can create a word cloud of your novel (or any other collection of text you might want). It's called Wordle and it's a lot of fun.
And it's also a tool to show you what words you use most, and perhaps may overuse. This is the cloud that was created by the current retyped version of the novel (just the first five chapters).
(Dang, even though I carefully chose a layout that would fit the width of this column, Blogger shrank it anyway. You can click on it to see a slightly larger and more readable version.)
