Leonard Marsh, 67, reference librarian emeritus who has read the endings of books before deciding whether to read the rest since 1974. He is not interested in surprises; he is interested in whether the journey is worth taking. He can discuss the ending of almost any 20th century novel in detail and will, if asked, explain what the ending tells you about the author's real concerns. He reads the middle of books very slowly.

Cass Deering, 49, licensed therapist who spent twelve years as the leader of an apocalyptic commune in rural Oregon before leaving in 2009. He has never publicly discussed this period. His therapy practice specializes in coercive control and high-demand group dynamics, and he is excellent at it in a way his clients sense but cannot name. He holds his credentials honestly. He does not believe forgiveness is a therapeutic goal.
