Just a word of caution from one writer to another... If you think you might want to publish this story, you may not want to put it on the Internet. Most publishers will not accept stories that have been published in any form, including the web.
An alternative may be to save that story idea and use it for NaNoWriMo (National Novel Writing Month) next month. I am still trying to come up with an idea for it. The website for NaNoWriMo is nanowrimo.org. It's kind of cool since several writers are trying to write 50K words in November. The forums and encouragement are great.
You may want to try a different book idea for Hubs.
Just a thought...
(Good Luck on NaNoWriMo if you sign up! I should go sign up myself now.)
