Line Theft! Iris White

Lucius creatively tries to stop Harry from inheriting the Black Headship, only just too late. Harry has no idea why or how, but he is pretty sure he once again barely evaded death. If only he didn't have to become a woman to do it... Given recent revelations, he decides to roll with it and tries to reinvent himself to some success. As a she, he figures the prophecy is a dud anyway.
