Mary Clare O'Brian is determined to be a saint when she grows up (the halo will help cover her frizzy hair). But lately none of her prayers seem to be working the way she wants them to: her mother is losing her faith, her parents can't pay all the bills, and her brother receives a draft notice for the war in Vietnam. Mary Clare has a plan to help, but it just doesn't seem to be working. How is she supposed to become a saint when her world is falling apart?
