Ghosted: A History of Ghost Hunting, and Why We Keep Looking, by Alice Vernon

From the publisher's website: A social, historical and scientific exploration of ghost-hunting, and why our fascination with the paranormal is as timeless as the ghosts we hope to find. The history of ghosts is ancient, but the history of active ghost-hunting is relatively recent, and investigations into the paranormal have developed hand-in-spirit-hand with scientific discoveries, from radio waves to smartphone apps. Now, more than ever, we want to find our own ghosts. Is it to help process grief? Become influencers? Or ease our fears of death?
