Author-to-Author is built around Catholic authors, but its real subject is the life of faith behind their books. Episodes usually begin with prayer. From there, the interviewer asks what led the guest to write, then lets the answer unfold at a patient, conversational pace. That can mean a childhood memory, a family loss, a devotion to Mary, a fascination with Church history, or a desire to explain theology in terms ordinary people can use. The show is not slick or hurried. It gives authors space to circle back, clarify, testify, and make connections between doctrine and daily life. A discussion of Janie’s Prayer becomes a conversation about Fatima, children’s religious imagination, illustrations, and the long influence of early formation. Cathy Garland’s Known opens into God’s identity, human identity, suffering, charity, and the comfort of a God who comes near. Michael Bluvas’s Sanctity brings in Catholic upbringing, moral judgment, prayer apps, artificial intelligence, and anxiety about technology flattening belief. Emily Hanlon’s Martha and Marya Mystery Series shifts the tone toward Catholic mystery fiction, parish life, friendship, foolish cops, and a purple-clad amateur sleuth. Diego Passadore’s Mary, the New Woman reaches into Scripture, the Ark of the Covenant, the Jordan, circumcision of the heart, Jewish texts, and the Dead Sea Scrolls. Other episodes lean on St. Therese, childhood experience, and disputed landmarks in Church history. The interviews are warm, sometimes digressive, and openly devotional. They are also practical. Theology is treated as something that shapes behavior, generosity, prayer, family memory, and the way a person understands time. Author-to-Author is best for listeners who enjoy Catholic books through human witness, not just summaries. Its charm is the way book talk keeps becoming spiritual conversation.
