Evelyn Barnes was supposed to be dead. For over seventy years, Bucky Barnes and Steve Rogers believed the woman they loved had been lost forever. They were wrong. Captured by HYDRA during World War II, Evelyn became the subject of brutal experiments that transformed her into something far beyond human. Telepathy. Mind manipulation. Reality-warping abilities. Powers so dangerous that even Wanda Maximoff fears them. When Tony Stark discovers a frightened young woman hiding from the world, he has no idea he's just found one of HYDRA's greatest secrets. Or Bucky Barnes' wife. As Evelyn slowly learns what it means to have a family again, old wounds begin to heal and long-buried memories resurface. But when an ancient creature known as the Harbinger arrives on Earth, a terrifying truth is uncovered. HYDRA didn't create Evelyn's powers. They stole them. Using DNA taken from the Harbinger itself, they turned Evelyn into a living weapon-and now something beyond the stars knows her name. With the Avengers at her side and darkness awakening inside her, Evelyn must uncover the truth before she loses herself completely. Because the greatest threat to Earth may not be the creature coming for her. It may be what HYDRA left behind. "They created the weapon. They never expected her to become something far more dangerous."
