An interview at the "Reading Catholic" website:
Q. As I wrote in my review, “If you’ve been through the loss of someone dear, Wish You Were Here will just make sense….Your’re fine, and then you’re not. You’re overwhelmed with sadness, and then you have hope. You cling to your faith, but you have doubts and questions and what-ifs.” Did you realize how much you were writing for so many other people when you wrote about your own experience of grief?
A. I didn't realize, but I hoped I was. That was the only reason to write it: to help other people. I don't mean that to be pretentious. It's just true. I was helped by other people's writing about their own experiences - everyone from the well-known like C.S. Lewis (A Grief Observed) and Kathleen Norris (Acedie) to simply bloggers sharing their own experiences of grief - that I hoped I could contribute a helpful voice to that never-ending conversation.
