A disappearing Aurora. A secret inventor. One small elf with the courage to save the North Pole. Tinsel is no ordinary trainee elf-she's curious, determined, and just brave enough to notice when something isn't quite right. So when the Northern Lights begin to flicker and fade, Tinsel can't ignore the feeling that something magical is going terribly wrong. With her brilliant friends by her side-clever Holly, mischievous Pip, and loyal Jingle-Tinsel stumbles into an adventure hidden beneath the snow. Strange tunnels, cracked crystal conduits, and forbidden mysteries all point to one legend: Eira Starpetal, the greatest inventor the North Pole ever knew... and the keeper of secrets long forgotten. As the Aurora weakens, dangerous tinkerers emerge from the shadows, puzzles guard ancient magic, and mysterious clues suggest that someone-or something-is stealing the Northern Lights' power. Armed with courage, cleverness, and a pouch of explosive jellybeans, Tinsel and her friends trek through icy caverns, stormy plains, and secret hideouts to restore the magic before it's too late. Along the way, Tinsel discovers that even the smallest elf can make the biggest difference... and sometimes the sky itself is listening. Can Tinsel, her friends, and a certain reindeer named Comet save the Aurora before the North Pole goes dark?The stars may know the answer-but time is running out. Perfect for fans of magical adventures, heartwarming friendships, and winter wonder, this tale will light up young imaginations like the Aurora itself.
