Ava Stark has lived five lives—and somehow kept every one of them separate. Panem knows her as Haymitch Abernathy’s daughter and a victor. Hogwarts knows her as a witch and the girl Fred Weasley loves. The Black Phone boys know her as the girl who survived beside them. Hawkins knows her as the mysterious girl Steve Harrington never stopped loving. And the Avengers know her simply as Tony Stark’s daughter. But when all five worlds suddenly collide, Ava’s families, friends, secrets—and every boy who has ever fallen for her—are about to end up in the same room.
