I've created a PDF of the book and now it's available for download free. It's also set loose upon the four winds under a Non-Commercial, Derivative Works, Creative Commons license.

What that means in English is, pass it around to whoever you like and remix it or play with the characters and worlds to your heart's content. Just a) don't make any money off of it, 2) keep the CC license attached to it and III) if you do play around with something, you have to release it under a similar license.

Enjoy.
