"The History of Spiritualism, Vol. II" is a book by Sir Arthur Conan Doyle, most famous for stories about the brilliant detective Sherlock Holmes. Doyle had a wide sphere of interests, including spiritual phenomena and life after death. This book is a detailed account of how spiritualism developed historically until the beginning of the 20th century.

A young writer travels to Maine to tell the unusual story of America’s longest-running camp devoted to mysticism and the world beyond. They believed they would live forever. So begins Mira Ptacin’s haunting account of the women of Camp Etna—an otherworldly community in the woods of Maine that has, since 1876, played host to generations of Spiritualists and mediums dedicated to preserving the links between the mortal realm and the afterlife. Beginning her narrative in 1848 with two sisters who claimed they could speak to the dead, Ptacin reveals how Spiritualism first blossomed into a national practice during the Civil War, yet continues—even thrives—to this very day. Immersing herself in this community and its practices—from ghost hunting to releasing trapped spirits to water witching— Ptacin sheds new light on our ongoing struggle with faith, uncertainty, and mortality. Blending memoir, ethnography, and investigative reportage, The In-Betweens offers a vital portrait of Camp Etna and its enduring hold on a modern culture that remains as starved for a deeper sense of connection and otherworldliness as ever.

Since its birth in 1848, Spiritualism as a religion, science, and philosophy has experienced great highs and lows. At the center of this purely American-made modern-religious movement are "mediums"--the people who are able to communicate, in some way, with spirit entities that are no longer on the earth plane. Based on three years of on-site investigation, and a plethora of data and research collected on the modern Spiritualist movement in America, Talking to the Other Side focuses upon the ethno-religious aspects of the religion, mediumship, and the mediums themselves. The first four chapters offer an expansive review of the history of religion in America, mediumship, and the Spiritualist movement. Chapters 5-7 comprise the research and data that were compiled and analyzed based on fieldwork analysis, a comprehensive questionnaire, personal interviews, and published literature on the topic of Spiritualism and mediumship. According to Spiritualist mediums, "people don't die, bodies do." Talking to the Other Side offers a contemporary look into the lives and backgrounds of the mediums who bridge this world and the Spirit world, connecting those who have passed over with those they left behind.
