NaNoWriMo and just kept going. Other people chimed in, we all joined hands and sang Kumbaya, discussed killing adverbs, overuse of literary cliches, and came to the conclusion that we might all be better writers if we started drinking heavily.
New Writer Person had a lot of faith in her writing, deservedly so, and took her NaNo story, chipped away at it, polished it, chipped some more, all the while showering agents and publishers with query letters and book proposals. And it paid off. She landed an agent who sold the book and got her a small advance that she should easily be able to out-earn.
The book is slated for a third quarter release this year; she posted the news and I posted back a genuine I-am-happy-for-you congratulations and promised to buy a copy on the day the book drops...to which she responded, "Thanks! If you ever get published I'll buy yours too!"
