The Unknown Garden of Another’s Heart

“If you want to see the meaning of true friendship in action, look no further than this inspiring book written by Joe Kohm! The lifelong, deep, and authentic correspondence between C. S. Lewis and his childhood friend, Arthur Greeves, is described beautifully by Kohm. New insights are here for fans of Lewis, scholars, and all who long for deeper relationships.”


—Joel Woodruff, President, C. S. Lewis Institute





“Joe Kohm has done us a great service by distilling hundreds of letters between two lifelong friends to give us deeper glimpses into their lives and the nature of friendship. Along the way, he explores the wonders of God’s grace, the nature of Christian faith, and the joys of spiritual growth. This book showed me things about C. S. Lewis I had not realized before and made me want to deepen my friendships.”


—Randy Newman, Senior Fellow for Apologetics and Evangelism, The C. S. Lewis Institute





“Kohm shows us what wonders ensue when one dares to cross a street to visit a sick neighbor. This exceptional work shows the secret garden of an abiding fifty-year friendship between Lewis and his homely and fascinating first friend, Arthur Greeves. Kohm chronicles how the mulch of letters fertilized key ideas and themes in Lewis’s thought, providing a fresh and welcome narrative of the power of friendship as a road to knowing God.”
