The Night Church - Whitley Stieber

Two congregations worship at the Holy Spirit Church. By day Catholics kneel at the altar of the tiny chapel in Kew Gardens, Queens.

But at night the rafters echo with Satan's music. Feared by the Vatican and as old as Christianity itself, a terrifying alternate religion has flourished in the darkness for two millennia, keeping alive the blood rituals of the Middle Ages while embracing the gods of high technology.

Preparing the way for the evil product of thousands of years of genetic engineering--the birth of the Monstrum--the anti-man and the death of humanity.
