In rural Italy, a priest keeps a dark secret beneath his chapel — a prisoner.

Only the elder holy man knows who this prisoner is and even the priest does not know how long he has been there — hundreds of years, perhaps, or even longer. His fear is that anyone in his parish would ever come in contact with his mysterious and unholy charge. But what happens is even worse than he could have imagined. His lovely young daughter, whose innocence and devotion to god he prizes over all else, trails her father into the cavern and catches a glimpse of the prisoner, a beautiful being like the most handsome of men and yet not. She looks in his eyes and sees pain and wisdom and eternity. Unable to keep away from this silent creature chained to an altar stone, she lives in fear that her father will catch her. One day he does and sends her off to America to be raised by her aunt in Boston. But she never forgets her silent love. Cover Him with Darkness is a thrilling story of an archangel banished from heaven and the human woman with whom he falls in love.
