Deus-X is a 1994 horror novel by American writer Joe Citro.
[1][2] The story ties together UFOs, government conspiracies, demonic possession, and Virgin Mary sightings, all with H. P. Lovecraft sensibilities.
[citation needed] The idea for the book came from Citro's love for and fascination with the occult and paranormal.
After researching and documenting countless ghost stories, UFO sightings, and general accounts of strange activity, Citro was struck by how interesting it would be if all these various phenomena were linked somehow.
Citro found himself chilled by those words and sought to write a story which exposed everything we thought to be true as devious manipulations.
