Mission: Christmas Star

Christmas is under attack in Maple Street-and ten-year-old Lila Harper is the only one who can save it. When Lila and her six-year-old brother Finn discover a mysterious glowing star hidden in their grandmother's attic, they unlock a seventy-year-old secret: the Christmas Star Promise. But with only twelve days until Christmas Eve, their family's holiday spirit is fading fast, and a sinister force known as the Black Star is consuming Christmas magic across their town.
Armed with cryptic clues, a treasure map, and the help of their grumpy neighbour Mr. Jenkins-who might not be so grumpy after all-Lila assembles Star Squad: a ragtag team of cookie-baking warriors, sword-wielding librarians, and one very determined golden retriever. Together, they must race against time to collect seven sacred Lights before the Black Star's master destroys Christmas forever. But when friends become enemies and the ultimate sacrifice is required, Lila discovers that the real magic of Christmas isn't found in lights or stars-it's found in the promises we keep and the people we protect.
The Promise never ends. The adventure has just begun.
