From the back cover
"Snatched by Satan himself from the fiery stake of a Salem witch-burning, a warlock lands right in the middle of a 20th-century Los Angeles. His age-old quest to bring about the reign of ultimate evil leaves a trail of blood and terror across America. Only one man can stop a witch hunter who has come from the past to stop the warlock and prevent the ultimate horror that will change the fate of the world."
Warlock is a sexually explicit, (sometimes) darkly funny and gory B-movie novel that expands on David Twohy’s fast-moving barebones screenplay by adding a more perverse sexual element, altering key characters’ physiques and personalities and a savagery that is hinted at in the film version. It is entertaining and worth owning, if you are a fan of the film and do not mind barebones plotting.
The film version was released stateside on January 11, 1991. It was directed by Steve Miner by a screenplay by David Twohy, billed as D.T. Twohy.
