Lewis, The Chronicles of Narina.
Waugh, Brideshead Revisited.
One of the most well-written novels of the twentieth century in the English language. The author, a devout Catholic, described it as a meditation on the irresistibility Divine grace.
Waugh, Sword of Honor.
Undset, Kristin Lavransdatter.
A great period novel set in 14th century Norway that explores a woman’s love affair with a knight and her life of faith. My spiritual director and a professor in seminary said that this trilogy helped them understand how a woman’s mind works. Having read them, I agree with their judgment.
Marshall, Sword and Serpent. Historical novel by Episcopalian priest convert to Roman Catholicism about Saint George set in the late third century.
T.S. Eliot, Murder in the Cathedral.
