A woman who wants to shrink her husband, but doesn't know how to tell him. A guy who has a crush on his new and lovely neighbor, and would love her to become his giant girlfriend. And a lifelong macrophile who just wants to see his impossible fantasy becoming reality. Sounds like hopeless dreams, right? Not for Claudia: she is Santa Claus's granddaughter, after all, and she has the power to make wishes come true, no matter how absurd. All it takes is one letter. And if you're really lucky, she will even come to you in person to become your personal giantess and mistress.
