New books on worship & mercy

Have you noticed the inordinate number of new books released the past few years (since 2007) that focus on worship and serving the poor?

To wit (from Christianbook.com):

• The Hole in Our Gospel by Richard Stearnes (Thomas Nelson, 2009)
• Servolution:  Starting a Church Revolution Through Serving by Dino Rizzo (Zondervan, 2009)
• The New Monasticism by Jonathan Wilson-Hartgrove (Brazos Press, 2008)
• The Dangerous Act of Worship by Mark Labberton, John Ortberg (IVP, 2007)
• When Necessary Use Words by Mike Pilavatchi (Gospel Light, 2007)
• Plunge2Poverty:  An Intensive Poverty Simulation Experience (New Hope, 2007)

Are there others you can add to this list?
