Cathy and Neasa,
Did you not know Dean Koontz is Catholic? In fact, his novel in the Odd Thomas series called “Brother Odd” takes place entirely in a Catholic monastery.
Raymond Arroyo is also a Catholic author, besides being a journalist, and has written a YA adventure (Will Wilder) series on Catholic relics.
Here is a link to Raymond interviewing Dean.
