Shadows and shining lights

At first, Michael and Christy think camping out in the backyard sounds like fun. But as night falls and the shadows grow, their fears send them burrowing deep into their sleeping bags. Then their guardian angel, G.T. (Good Tidings), makes a timely, if unusual, entrance. As he helps them to understand the wonder of angels, they learn, too, that angels are sent by God to protect us.
