“Ghosts are always hungry,” someone once said—and no one knows how ravenous they really are more than Ed & Lorraine Warren, the world’s most renowned paranormal investigators. For decades, Ed and Lorraine Warren hunted down the truth behind the most terrifying supernatural occurrences across the nation... and brought back astonishing evidence of their encounters with the unquiet dead. From the notorious house immortalized in The Amityville Horror to the bone-chilling events that inspired the hit film The Conjuring, the Warrens fearlessly probed the darkness of the world beyond our own, and documented the all-too-real experiences of the haunted and the possessed, the lingering deceased and the vengeful damned. Graveyard chronicles a host of their most harrowing, fact-based cases of ghostly visitations, demonic stalking, heart-wrenching otherworldly encounters, and horrifying comeuppance from the spirit world. If you don’t believe, you will. And whether you read it alone in the dead of night or in the middle of a sunny day, you’ll be forever haunted by its gallery of specters eager to feed on your darkest dread.

The story of the most terrifying case of demonic possession in the United States. It became the basis for the hit film “The Haunting in Connecticut” starring Virginia Madsen. Shortly after moving into their new home, the Snedeker family is assaulted by a sinister presence that preys one-by-one on their family. Exhausting all other resources, they call up the world-renowned demonologists Ed and Lorraine Warren—who have never encountered a case as frightening as this... No one had warned the Snedekers their new house used to be an old funeral home. Their battle with an inexplicable and savage phenomena had only just begun. What started as a simple “poltergeist” escalated into a full-scale war, an average American family battling the deepest, darkest forces of evil—a war this family could not afford to lose.

The legend of the werewolf is as old as man himself. From Ed and Lorraine Warren, the world’s most famous demonologists, comes perhaps their most incredible and horrifying case: the true story of William Ramsey, whose bizarre seizures terrified the English town of Southend-on-Sea. Believing Ramsey to be a victim of demonic possession, the Warrens arranged for the rite of exorcism to be performed. Not since the exorcist shocked the nation has there been such a such a horrifying account of a supernatural battle between good and evil within the soul of one human.
