Kidnapped as a child and presumed dead, Kaley Stark—Tony Stark’s younger sister—was taken by the Red Room and forged into a living weapon. Unlike the other Widows, Kaley harbors something they couldn't program, something they couldn't break: a strange, dormant power tied to an ancient force known only as the Void.
Raised alongside Natasha Romanoff and trained in the cruelest conditions, Kaley survives not by surrendering to her conditioning—but by mastering it. Now, as shadows move and secrets stir, the girl they tried to erase is waking up.
She remembers who she is.
And the world is about to remember her too.
