I have always been obsessed with real-life hauntings, whether the spirits reside in manors, castles, hospitals, or mental asylums, so I veer towards any book about "true" ghosts and spooks. However, if I were ever to be confronted by a spirit, I would most likely be traumatized for life, but that doesn't stop me from loving books about them.
Richard Estep is a respected paranormal investigator who writes lots of books about real (and presumed) hauntings. His books are a fast and fun read for anyone wanting to get their spook on, and this is no exception. In this book, Estep covers many known and lesser-known hauntings, providing a bit of history and sometimes including his own discoveries with fact-based findings (sometimes the experiences of others don't always live up to being proven), with photos. This is a great book to have handy for reading spurts.
Other books I enjoyed by this author are "Asylum 49," which is based on an infamous haunted nursing home/hospital in Utah, and "Spirits of the Cage," which is based on a medieval prison.
Perfect for fans of TV "reality" shows such as Ghost Adventures and Ghost Hunters, and the podcast, "Spooked."
