Not a biography but a critique from a late modern perspective of aspects of Lewis's theology, in particular issues of God's sovereignty in light of evil and suffering, prayer, miracles, the supernatural and the afterlife.
Some of this critique was insightful, particularly in reflection upon Lewis's moralism, but other critiques are clearly simply reflective of the author's context and worldview (i.e no place for weird Christianity).
