She lives. Deep in the bowels of the underworld Alyda the half-human demon waits to return to the earthy plane. This horror sequel chronicles her blood-soaked ascent. It all begins at Miskatonic University where several gruesome murders have occurred. Two college students, Randolph Carter and Eliot Damon Howard witnessed some of Alyda's handiwork in nearby Winthrop mansion where their friends, who went up there for a little illicit fun, were mysteriously slaughtered. The fleeing duo encounter the cops and paramedics. Though they claim some otherworldly monster is responsible, Sheriff Hatch pooh-poohs them, claiming an animal did the damage. Howard goes to the hospital and while there has a vision. He sees the original owner of the mansion who lived in the 1600s. The owner had been a warlock and it was he who awakened Alyda. As Winthrop fades, he warns Howard that he must stop her. Unfortunately, after his release, Howard has trouble finding people to believe him until he and Carter hook up with professor Harley Warren who uses a combination of ancient rituals and modern technology to take care of Alyda once and for all, but not before more blood is spilled and much horror ensues. Both this and its prequel were based on tales byH.P. Lovecraft.
