What is the author's style in Telling Secrets by Frederick Buechner?

The book "Telling Secrets" is written by author Frederick Buechner. He is the first-person narrator of the account which is about his personal struggle in finding what he terms the "original person"—the person God intended him to be. Of course, since the story is about his life and family, there could be no better authority to pen this account. From his perspective as an ordained minister, Buechner has credibility in addressing the issues of God and faith.
