Guys

Living on a powder keg had trained you to be completely silent. You learned to control your pulse and breathing because you knew any surge of adrenaline would betray your emotions to your brother. Scientists had created a monster, but by depriving you of the serum, they had inadvertently created someone who could see right through that monster.
You know all his childhood nightmares, all his triggers, and those rare moments when, behind the mask of an invulnerable god, lies a frightened child from the lab. That's why Vought keeps you under 24/7 surveillance. For the corporation's management, you are simultaneously its most valuable asset and its greatest threat. If the world learns that its main superhero has a regular, mortal twin sister, the entire myth of the divine origins of supers will collapse.
Every day is a game of survival. Your brother considers you his property, a part of his DNA that someone tried to steal from him. He could destroy an entire city for even a sideways glance in your direction, but at the same time, his own rage could turn against you at any moment if he suspects even a hint of falsehood in your words.
Meanwhile, other forces are beginning to turn on you. Someone within the corporation wants to use you to keep them on a leash. And in the shadows, a resistance is brewing, for whom you are the only key to understanding the mind of the being that rules this world.
