For a fun ride into basic apologetics to Evangelicals, try Martin De Porres Kennedy’s tale, " A Philadelphia Catholic In King James’ Court". It’s the story of a Catholic youth (late teens?) sent for a summer to live with an evangelical relative whom he respects, and his struggle to learn to offer up a reason for his Catholic Faith.

I have been working my way through the fictionalized but historically based novels of Louis de Wohl on the major Saints of Our Faith. They are great reading! I’m in the Augustine one now.

I have also heard wonderful things about this book but have not read it yet. The Red Horse, By Eugenio Corti
Other titles to enjoy:
Lilies of the Field by William E. Barret: short and sweet with no sermonizing. Also made into a good film.
In this House of Brede by Rumer Godden. This book was instrumental in my conversion to Catholicism.
Brother Cadfael series by Ellis Peters. These are also available as a television series produced by the BBC. Our local public library carries them and our kids LOVE them.
Kristin Lavransdatter: The Bridal Wreath, the Mistress of Husaby, the Cross ( set of three titles) by Sigrid Undset.
Virtually anything by G. K Chesterton, C S Lewis, and JRR Tolkien.
I personally also enjoyed The Sparrow and The Children of God, by Mary Doria Russell, but warn you that 1) they are serious Sci Fi and 2) they deal with some rather graphic events of a sexual nature. They do depict Catholic priests in a good light, well into the future when other worlds have been discovered.
