On 11 Nov. 1981, the Potter twins, the Girls-Who-Lived, died. On 1 Sept 1991, that's revealed to be a lie. Hattie & Euphie didn't die, they survived and have spent ten years hiding in the Muggle world. Now, though, they've returned, and nothing at all is as it should be. Ev. TMR/HP.

In which Lettie Potter is Sorted into Ravenclaw when she pleads "Not Slytherin", Voldemort is smart enough to only make three horcruxes, and Snape just can't make himself hate the girl who keeps showing up bloody and bruised on his doorstep.

What if instead of a son, the Potters had twin daughters? What if Voldemort's horcruxes had managed to gain themselves bodies in his absence? What if nobody knew which sister was destined to save the world?
