There has always been something wrong about All Hallows Church. Not just the building, but the very land upon it stands. Reports dating back to Roman times reveal that it has always been a bad place—blighted by strange sightings, unusual phenomena, and unexplained disappearances. So in the 1990s, a team of para-psychiatrists is sent in to investigate the various mysteries surrounding the Church and its unsavoury legends. From the start, they begin to discover a paranormal world that defies belief. But as they dig deeper, not only do they uncover some of the secrets behind the ancient edifice designed by "Zombie King" Thomas Moreby but, hidden away beneath everything else, something so ancient and so terrifying that it is using the architect himself as a conduit to unimaginable evil. After four days and nights, not everybody survives—and those that do will come to wish they hadn't. Imagine The Haunting of Hill House, The Amityville Horror, The Entity and The Stone Tape rolled together into the very fabric of a single building. And then imagine if all that horror is accidentally released . . .

In his house at R’lyeh dead Cthulhu waits dreaming. The Armies of the Night are rising. Such clandestine cults as the Olde Fellowes and the Esoteric Order of Dagon, who worship a group of ancient deities called the Great Old Ones, are harnessing occult powers to open the doorways to the Dreamscape and other dimensions beyond space and time. Now something big is coming—something that is already sowing the seeds of madness and chaos into the psyche of the world—and only the agents of the Human Protection League stand between this rising tide of evil and the enslavement and eventual destruction of the human race itself . . . Set against such historic events as the assassination of President John F. Kennedy, San Francisco’s “Summer of Love,” the first Moon landing, the rise of the Civil Rights Movement, and the Watergate break-in, the dedicated members of the Lovecraft Squad battle supernatural threats all across the world—and from beyond the stars.
