C.S. Lewis takes a visionary bus ride from hell to heaven with his fellow dammed souls. Each is met by someone and given the oppurtunity to walk freely into heaven, although most choose rather to rule in Hell than reside in heaven. Lewis witnesses the choice itself being made in various manisfestations, and given a tour by George MacDonald - Lewis's own spiritual guru in real life. This book is not a metaphysical treatise on heaven and hell, it is a clever and insightful look into our free will and why we choose ourselves over God, why we keep our misery when we are offered joy. You will be profoundly affected by this book and it will shape the eternal choices that you make.
