Nine-year-old Kelly Donovan helped save the world from aliens, but now, she has an even bigger problem - someone’s trying to ruin Halloween.

Life is difficult for the world’s tiniest superhero. Her genius plan to save her parents from supervillainy in one easy step proved impossible - at least not without destroying the Earth. Superpowers, good or bad, aren’t going away any time soon.

Mom’s as likely to hug her as trick her into a ridiculous trap, but at least, her dad’s mellowed out a bit. Lately, he seems focused more on being weird than evil.

Small favors.

Kelly’s looking forward to the happy normal of trick-or-treating...until candy starts disappearing. Convinced a mysterious supervillain is responsible, she and her best - only - friend Paige rush to stop all the sweets in the world from evaporating.

Alas, with only a week left and zero clues, humanity will likely suffer an even worse fate than enslavement by an alien race: the end of all Halloweens.
