When Anna’s dad leaves her a beautifully wrapped Christmas gift with strict instructions not to open it until morning, she never expects her scheming stepmother, Melanie, to tear into it first. Melanie’s greed sets off a chain of unexpected events—karma for Christmas.

Christmas used to be my favorite time of year, filled with twinkling lights, gingerbread cookies, and the smell of fresh pine. But since my dad remarried a few months ago, his new wife, Melanie, has made me feel like an outsider. While she isn’t outright evil, her sweet smile often hides comments that undermine my confidence, like, “Oh, Anna, is that what you’re wearing?”

I kept quiet for Dad’s sake, as he seemed genuinely happy, and I didn’t want to ruin it. After losing my mom ten years ago, I convinced myself I could tolerate Melanie if it made Dad feel less alone.

That changed a week before Christmas when Dad handed me a beautifully wrapped box, saying, “I have something really special for you this year.” I was excited to unwrap it, but he asked me to wait until Christmas morning. Meanwhile, 17-year-old Rosalie faces her own challenges when her stepmom, Susan, sabotages her Christmas by canceling her flight. However, karma intervenes, leading to a series of ironic twists that leave Susan humiliated and ensure her Christmas is far from perfect.
