Dietrich Lagrange is destined to become the story's most evil villain, in a family where everyone cruelly vies to claim their place as its head. But somehow, Anissa is worming her way into his cold, shut-off heart. Little does he know that she's actually a reader reborn as his baby sister. No matter what happens, she plans to survive the story rather than live out her character's original deadly fate!
