Across the Bridge Between Worlds Who were Darby and Joan, the mystery couple investigating what some consider to be the paranormal, while many others would consider their experiences to be extraordinary and awe-inspiring but within the norm of the human experience? And who was "Stephen," the dead man who became the subject of their 1920 book? Within the book, Our Unseen Guest, you will come to know who they were, and also you may learn more about life, life after death, and how consciousness lives on after the death of the physical body. Linda Pendleton, author of fiction and nonfiction books, has written a new Introduction to this fascinating story of three people and their journey across the bridge between worlds.
