What Has Happened To Santa Claus‪?‬

It's the beginning of December and not only has Petrella fallen out with her best friend over a stupid presentation for school but her mother also gives her the most horrendous advent calendar Petrella's ever seen.

She soon discovers, however, that this calendar allows her to speak with Santa's elves, who send her on a quest to save Santa who's being held prisoner at the South Pole!
