The evil continues in this sequel to the New York Times–bestselling The Sentinel

Satanic forces return to an apartment building on Manhattan's Upper West Side with the discovery of a grotesque, charred body and two other eerily linked murders. When the young woman who stumbles upon the body is raped, her husband begins a furious quest for revenge. Meanwhile in the building, a blind and paralyzed nun with sinister intentions stares vacantly out of an upstairs window and a cunning priest tries desperately to save more innocent lives from destruction. Full of hellish twists and turns, The Guardian is a story of what happens when you come face to face with evil incarnate.
