I've shared a few novels in progress before, mainly "Long Road from Canaan", and "Regrettably a Gentleman", that seem to disappear, never to be heard from again.
(Just so you know, they might pop up again, after some major replotting and such)
But, I'm feeling pretty excited about "Mithras & Myrrh", as I'm about 57,000* words into my first draft, and still writing steadily onward!!!
