The Piercing by John Coyne
Betty Sue is an innocent young girl who acts out the agony of Christ once a week. It is haunting and fascinating to millions. The TV says it's a miracle. The Church says it's fake. But this is no charade — from her head, hands, feet and side pours her blood. Witnessing this agonizing phenomenon is Father Stephen Kinsella, a Catholic priest whose faith is already unsteady. Is she divine? Or damned?
