ⓘ About Gary McAvoy

Gary McAvoy is a crime fiction and thriller author from the Pacific Northwest, even though he is originally from California. He penned “The Magdalene Deception,” the first novel of the “Magdalene Chronicles” series in 2020. McAvoy had always been interested in storytelling since he was very young but his interests in entrepreneurship had taken over for years. He wrote his first story as a ten year old and was determined to become an author from that time. Gary grew up in a large Catholic family and hence he was always fascinated with the Vatican and how much influence it had all over the world. He also studied the many people who worked in its name to do God’s work.
