If not for this three-minute commentary on National Public Radio’s Morning Edition on Oct. 20, 2005, the book shown here would not exist. While my commentary aired, Randi Murray, a literary agent in San Francisco, listened in her driveway. She told me that when she finished crying, she dashed into her house, looked me up on the internet and sent me an email, which said in essence, “There’s a book in that commentary if you’re interested, and I’d like to represent you.” I spoke with Randi after returning from Italy with my family after the canonization. She coached me through the process of producing a 50-page book proposal over the next few months. And in March 2006, she negotiated a contract for me with a division of HarperCollins. When I look back on all that — how it started and what it produced — I’m left with only one reasonable explanation: It was a miracle.
