I was introduced to the series as a high school freshman. I enjoyed the text very much at that time (even though I was working with a photocopy). I was equally impressed with the Sophomore text when I taught with it nearly ten years later.

The first book, Our Goal and Our Guides, focuses on understanding our goal in life – attaining Heaven – and spiritual and doctrinal issues that are related to that goal (such as the roles of faith and reason, the liturgical year, the Blessed Trinity, the Fall, and Salvation through Christ).

The second book, Through Christ Our Lord, studies the life of Our Lord in great detail - covering the Old Testament time of waiting for Christ, the basic events of Christ's life, a detailed study of Christ's Death and Resurrection, the Eucharist and the Mass, the Sacraments and following Christ today.

The Ark and the Dove (Book Three) covers the Catholic Church and the Holy Spirit. 

Towards the Eternal Commencement is designed especially to prepare graduating seniors as they go out into the world. It covers Our Lady; considerations about death and the afterlife (best reflected upon earlier in life!); vocations; those commandments, virtues and teachings important for "building a better world" and a segment on Apologetics.
