Mabel and Billy are two young children who live at the base of a mountain. Mabel wants Billy to do as she says, because she believes she knows best. Billy wants Mabel to listen to him, because he feels he is the one who knows it all, and that he has nothing left to learn. Mabel and Billy both set out from their houses one morning, ready to fight for their way. After accidentally starting an avalanche, they are saved by a man in glittering robes. That man turns out to be Jesus. Jesus spends the day with the children, walking with them and teaching them many lessons. In the end, they learn that they are not so different, and that there is always value in listening and learning. They are both filled with Jesus' Light, and they set out to spend their lives sharing His story with others. Mabel & Billy is the third book in the trilogy that includes Wee3 and Jack.
