I heard from my publisher last week, who had some positive news. They met as a committee and they like the book idea. Now what needs to happen is obtaining some numbers and reports on marketability, financial viability, and target audience, to see if it will work. I'll hear back in 3-4 weeks.
For those of you who are new to Introverted Church, I sent in a book proposal to a Christian publishing house back in June. Go here for the chapter outline of my idea. I always love feedback.
