For fans of Mercy Watson, old and new, comes a joyful crescendo of favourite characters in a picture-book celebration of the quiet miracles Christmastime brings.

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 chocolate and a stack of well-buttered toast.
