A resilient and quirky colony of church mice fears another Great X more than they fear cats. Under Mouse Mistress Hildegarde's leadership, they save themselves from one danger after another—sometimes just by the skin of their tails! Can one ultimate act of bravery during the feast day of St. Francis get Father Murphy to bless these mice and keep them safe forever? Rife with humor and personality, this young middle-grade novel has an old-fashioned feel with the makings of a modern classic.
