The story: the night before the tree-lighting ceremony, every string of lights vanishes from the town square. Jake, Scout, Milo, and Ben follow a trail of tangled wire, footprints in the snow, a cane mark, a red mitten, and one unbroken red bulb to Mr. Rowan's house - a lonely elderly neighbor who took the lights to see them shine once more, the way they did when his wife was alive. Hot cocoa, a plan, the whole town rehanging the lights, and Mr. Rowan gets the honor of flipping the switch.
Invented details are yours to veto: Mr. Rowan, Mrs. Hartley (the ceremony organizer), the clues, and the handmade wooden star ending. In the art, Mr. Rowan wears glasses and a flat cap that aren't in the text, and the Chapter 2 "bare tree" came out as a leafless tree rather than a bare evergreen.
