When Mia’s stepmother, Trudy, decided to throw herself an extravagant party for her 45th birthday, Mia knew she’d be roped into the role of an invisible helper. Little did Trudy know, karma was on Mia’s side, waiting to dish out a lesson she’d never forget.

Get ready, because this is one of those moments where the universe steps in at just the right time, and let me tell you—it’s satisfying.

Meet the main characters: I’m Mia, a 16-year-old living with my dad and stepmom, Trudy. Trudy’s been around for about two years now, and she’s nailed the “wicked stepmother” role like it’s her job. If entitlement had a mascot, it would be Trudy.
