This biography investigates the life, intellectual development, and creative output of C.S. Lewis, one of the most influential Christian apologists and fantasy authors of the twentieth century. Roger Lancelyn Green and Walter Hooper, both close associates of Lewis, utilize their intimate knowledge and access to personal archives to construct a comprehensive portrait of the man behind the Narnia chronicles. The authors trace his trajectory from his early life in Belfast and his academic career at Oxford to his profound religious conversion and subsequent literary success. By synthesizing personal correspondence, diaries, and academic records, the text provides a detailed examination of the influences that shaped Lewis's worldview and his contributions to English literature.

This work is widely regarded as a foundational text for scholars and enthusiasts seeking a primary-source-heavy account of Lewis's life. The authors' proximity to their subject provides an unparalleled level of detail, though the narrative maintains a respectful, appreciative tone throughout the biographical account.
