Ash Wednesday is a day of fasting for the faithful when they receive the sign of the cross in an effort to bring others to the church.

In desperation, Mary turned to the church, insistent she'd been possessed by a demon. Can a visiting priest at St. Michael's help save Mary's soul? In Angel Hill, nothing is certain.
