Every Christmas, in the heart of a little town, there stood a magnificent red postbox. They called it The Jingle-Jangle Postbox, because every letter slipped inside was answered with a joyful ring, a magical sound that promised wishes heard. But this year, the Jingle-Jangle Postbox was silent. Eight-year-old Leo, new to town and feeling quite lonely, pressed his ear against the cold metal, hoping for a jingle to answer his quiet wish for a friend. All he heard was silence. That is, until he discovered a dusty old toy shop and its reclusive owner, Mr. Hemlock - the very toymaker who built the magical postbox long ago. Mr. Hemlock, too, seemed to have lost his own "jingle". Can a curious boy and a forgotten toymaker mend more than just a broken machine? Journey with Leo and Mr. Hemlock as they search for the lost jingle, and discover that the most magical sound of all comes from friendship.
