Three unique Christmas tales show the least accepted of us finding Christmas as a worthy task to endure. In “Not Candyland,” an often unmanageable foster girl learns love can be earned, both by her and for her. In “The First Black Sheep,” a boy with a muscular disease experiences a classic fable. In “Destinations,” an aged homeless woman, a drug addict and a vicarious listener share a Christmas gift untangled by materialism. Under the Christmas Three extends a series of Christmas stories not so much meant to inspire as meant to reveal.
