Mercy Mathers looks like a blonde angel, but everyone knows she’s the wildest party girl in Clarion High. But when her boozy, slutty antics cause the death of nearly the entire high school football team’s starting line-up, Mercy seeks forgiveness by way of religion. Once she’s saved, Mercy feels compelled also to save the bad boys she once sought out for her own pleasure. Now she offers herself to compel them, too, to find the Lord. But bad boys tend to be bad, and to prevent them from backsliding, Mercy has to sacrifice them before they can fall from grace. But what guy would ever guess that the sexiest, most beautiful girl in school is a homicidal maniac on a mission from God?
