I think you are referring to Ms. Rice's current bestseller, "Christ the Lord: Out of Egypt." Ms. Rice has undergone a profound conversion experience, returning to the Catholic faith of her youth. Her Afterward in the novel chronicles her journey to Christ. It's quite inspiring.
More pertinent to the debate on this thread, that amazing Afterword of Ms. Rice's documents her spiritual journey BY MEANS OF A LONG THOROUGH REVIEW OF THE LITERATURE ON THE RELIABILITY OF THE NEW TESTAMENT and her shock at realizing that the evidence supports the orthodox view.
That chapter by Ann Rice should be read aloud in every church on Easter morning.
Read it for her magnificent comments on the skeptical arguments; read it for her very perceptive list of recommended NT scholars. You know she has a good head on her shoulders solely from her respect for NT Wright.
I'm also reading "The Resurrection of the Son of God". Every generation has one scholar who destroys the skeptics of NT literature; Wright is ours.
And there is simply no reason to doubt that Paul of Tarsus wrote the pastoral epistles, other than the purely circular assumption that the church depicted therein didn't exist then.
