"The Cambridge Companion to C.S. Lewis succeeds in its purpose, scope, and coverage as a winsome, informative, and informed volume to accompany novice and veteran readers of Lewis in their pursuit of his insight and its source. Essays that both instruct and delight in Lewis studies are few; we can be grateful that under one cover, MacSwain and Ward have gathered so many."
VII: An Anglo-American Literary Review
"… the volume succeeds in bringing fresh insight. Lewis is engaged as a serious writer who sought thoughtful response, rather than applause from uncritical fans. One major strength is a thoroughgoing tendency to see Lewis's work as a whole, noting ways different books in different genre inform each other."
William Frantz, Anglican Theological Review
"… succeeds in conveying the richness and complexity of Lewis' thought with an appropriately commendable depth, clarity, and imagination."
Jason Wardley, The Expository Times
