I never thought I'd wake up as Anna, the hated "villainess's little sister" from my favorite novel. But here I am. And guess what? My future is already written, death by execution for crimes I didn't commit. Yeah, no. There is no way I'm letting that happen! When I discover my "Saint" of a sister is hiding dark secrets, I decide to fight back. My only hope? Luca, the strongest knight in the kingdom and my sister's fianc. But as I dig deeper into my sister's lies, I uncover shocking truths about our family that change everything. From oppressed sister to true heroine, this is the story of how Anna awakens, takes control of her destiny, and turns a tragic fate into her own rise to power.
