It's been almost six months since Amirah visited the Magical Land of Birthdays, which means it's almost time for her half-birthday! As that special day approaches, she realizes something is not right in the birthday universe. Party invitations are going missing, people don't feel like celebrating, and stores are sold out of birthday cake ingredients.

When Amirah notices that the pages of The Power of Sprinkle are fading away before her eyes, she knows something is terribly wrong. That's when she and her B-Buds new and old travel back to the Magical Land of Birthdays, where they discover that someone is determined to rid the world of birthday magic--by destroying the Magical Land of Birthdays! Can Amirah and her B-Buds restore the magic before it's too late?
