In 1943, an Asgardian goddess came to Earth searching for a simple life. Instead, she found love in the arms of Sergeant James Buchanan Barnes, friendship with Steve Rogers, and a family among Peggy Carter and Howard Stark. She never revealed what she truly was. Then Bucky fell from Zola’s train. Steve disappeared beneath the Arctic ice. Heartbroken, she returned to Asgard. Seventy years later, she’s an Avenger—and when rumors begin circulating of a ghost-like assassin with a metal arm, she finds herself chasing someone she buried long ago.
