Elena Gilbert was the girl everyone loved. Morticia Gilbert was the girl everyone feared. Twins by blood. Strangers by choice. While Elena grew up surrounded by love, Morticia was raised in the shadows of Augustine, where experiments, monsters, and broken promises shaped her into something the world was never meant to see. Now, Mystic Falls only knows one version of the story-and Elena made sure of that. Labeled unstable. Dangerous. Insane. Morticia has spent years wearing the mask everyone expects while hiding the truth about the father who destroyed her and the sister who never believed her. But secrets don't stay buried forever. As vampires, Originals, witches, and hunters collide, the forgotten Gilbert twin is about to remind Mystic Falls why monsters aren't always born. Sometimes, they're made.
