This is a scene-by-scene/each-year-a-chapter biography by a Harcourt Brace Jovanovich/Macmillan editor. I wasn’t really ready for another Lewis biography, having just finished The Narnian (in February 2012, discussed elsewhere on this site), so I just read the introductory material and chapter 1 (“1925”) and then all that piqued my interest from the index entries.
