The Kindle release date is October 27, but you can pre-order it now for only $0.99. That price will stay through the end of the month before it goes to regular price, so grab it while it's cheap.
The paperback will be available December 3, possibly sooner. In the meantime, if you haven't already, you can sign up for email updates and get the first chapter free.
Oh, and Happy Canadian Thanksgiving!
