Considered one of Frank Sheed's best books, A Map of Life is also regarded as one of the best and most popular short summaries of the Catholic faith ever written. Focusing on the major truths of our existence and purpose in life, Sheed draws on God's revelation to show what the divine master plan is for us and how each part of the plan is related.

Beginning with "The Problem of Life's Purpose" and "The Problem of Life's Laws", he covers such important parts of the map of life as "The Creation and Fall", "The Incarnation", "The Mystical Body", "The Trinity, "Law and Sin", "The Supernatural Life", and Heaven, Purgatory, Hell.
