For fans of Mercy Watson, old and new, comes a joyful crescendo of favorite characters in a picture-book celebration of the quiet miracles the holidays bring. Mercy ornament included! Stella Endicott felt joyful. She felt like something miraculous might happen. She wanted to sing. 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? With tender affection for Mercy Watson and all her Deckawoo Drive friends, Kate DiCamillo and Chris Van Dusen offer a picture-book homage to the season that is perfectly suited for family sharing--perhaps with some cups of hot cocoa and a stack of well-buttered toast.
