Book Recommendations

I'm going to start a series of book recommendations on this blog. As I talk to other small group pastors or folks trying to learn discipleship, I find that I'm pointing them to Activate or Simple Small Groups or Building a Church of Small Groups.

So...I'm going to start providing some short posts to include recommended audience, primary message, and summary of main points.

And while we are talking about it, what books do you recommend that discipleship pastors, small group coaches, and small group leaders read?
