Petra just loves spring in Gimmelwald. Each season she and her family lead their prize dairy cows into the pastures to graze and each cow wears her own jingling, jangling, clanging bell. What a symphony! But when Petra's favorite cow, Effie, loses her bell the whole herd is out of harmony and refuses to move. Will Petra be able to find Effie's bell before it's too late? With charming illustrations, this whimsical story is sure to delight children and adults alike.
