The first corrections are rolling in. It is amazing that I can miss such obvious gramatical mistakes and misspellings, especially after reading and editing so many times (and with so many sets of eyes having read this before!).
There is no greater help to a writer than volunteers willing to read the work, to critique, to ask all the questions you thought you'd answered, to point out that a character's name is spelled one way in Chapter Four and a different way in Chapter Twenty, to tell you exactly how your science fiction science could never work. Feedback is essential. You discover just what you've accomplished versus what you hoped to accomplish. Then your job is to close the gap. (Or, in some cases, cast aside what you were trying to accomplish the first time because the readers saw something even cooler.)
Every day I get a little closer. Thanks, everyone, for the help and support. I hope to eventually thank everyone properly.
I've just finished compiling the .epub, including this awesome cover from Phineas X. Jones. I've contacted several generous beta readers who will look for formatting issues and the like. Some of them have read several versions of Comet Jack, so I don't use the word "generous" lightly. This is my last chance to catch anything boneheaded that has made it this far into the project. The step after this one is... going live.
