Everyone thought Steve Rogers' little sister was dead. Bucky Barnes had spent years believing the same thing. Before the war, she had been the girl he secretly loved—the one person he could never bring himself to confess his feelings to. Then she disappeared. Years later, the Avengers encounter a dangerous HYDRA operative known only as Wraith. A masked woman with a matte-black metal arm. A weapon with no memories of the life she once had. Until Steve recognizes something behind the mask. And Bucky realizes the woman standing in front of him might be the girl he thought he lost forever.
