In one universe, Thanos wins. Wanda Maximoff and Vision die. But their daughter survives. Unable to live in the timeline that took everything from her, Petra Maximoff does the impossible-slipping between universes in search of one where her parents are still alive, because the fate that took them from her is too difficult to face. When she finds it, no one here knows who she is. But Petra knows them. She knows the future waiting to break them. With the reluctant help of the Guardians of the Galaxy, she returns to the people she lost-a stranger to the parents who once knew her, even as Wanda can't shake the quiet feeling that something about the girl feels impossibly familiar. Along the way, Petra meets Robert Reynolds-a man carrying a power bright enough to rival the sun and a darkness just as dangerous. The more they uncover about themselves, the clearer it becomes their powers were never meant to exist alone. The universe rarely lets fate be rewritten so easily...especially when the girl trying to change it may be something far more powerful than anyone realizes. Petra refuses to let this story end the same way twice.
