Q & R: Books for Advent?

Here’s the Q:

I was thinking ahead to Advent. Do you know of any books that would be good for a congregation to read/ponder/discuss for that season of our life together? I have often used Merton’s Seasons of Celebration during that time.
PS Please remember that you changed my life, and my wife’s, forever and helped us begin to go on the journey and joy of discovery!

Here’s the R:
Of the things I’ve written, I think We Make the Road by Walking would be the best fit.
Chapters 14-18 are specifically about Advent – I could imagine a congregation doing Chapters 1-18 too.
Thanks for the encouraging words! We’re in this together!
