As a biography for middle-grade students in the early years of C.S. Lewis' growing impact, this is faithful, well-written, evocative, and short. Regular readers of Lewis biography won't find much new here as 2/3 of the book is a retelling of Surprised by Joy.
This is a compelling biography of C. S. Lewis emphasizing his growth from boyhood (including loss of his mother at an early age and a father unable to connect emotionally, a brother with whom he was closely connected) and how he both lost and gained faith during his school years until he became an author famed for both adult and children's books showing his zeal in the Christian faith after adopting Christianity as an adult. It encompasses his years at private school, time serving in the Great War, influence of his many friends (many famous) all of whom were "good" - chaste, honest, loyal, learned, and mostly Christian, life during WWII and after. Filled with quotes from letters Jack wrote to his friends and family as well as quotes from others about him this is as fascinating in an historical perspective as it is detailing his personal growth. This is one I'd like to add to my personal library.
