When Stella gets the sudden idea to go caroling, she has a little trouble getting someone to join her. Her brother, Frank, is not good at spontaneity. The Watsons are very involved in a precarious fruitcake attempt (but happy to send their pig, Mercy, out for the occasion). Eugenia Lincoln declines, a bit rudely, to accompany on her accordion, and Horace Broom is too busy studying planetary movement. Will Stella need to sing by herself--with enthusiastic contributions from the pig, the cat, and the horse she picks up on the way? Or does the evening hold a miracle Stella hadn't expected?
