"When the Well Runs Dry" builds on Green's classic and bestselling primer on prayer "Opening to God". It encourages readers to re-examine their perspectives on prayer and argues that prayer has less to do with what readers do or know and more to do with what God does in them. "With kind humor and easygoing compassion, this Jesuit explains how to find our way through the "dark night of the soul," those weeks, months and sadly, even years when God's face seems inscrutable." - "Weavings".
