A Change of Fate (гет)

Paige Potter, the Girl-Who-Lived, is used to her life being weird though she hoped with the Dark Lord's defeat she could regain some level of normality.
Unfortunately, the universe still has it out for her.
One duel with Death Eaters and a curse later, she and her best friend Hermione find themselves in an alternate universe where the Girl-Who-Lived is now the Boy-Who-Lived and, oh, it just so happens to be October 31st, 1981.
Unwilling to let what happened in their timeline happen here and determined to protect and raise the Boy-Who-Lived in a loving home Paige (along with an exasperated Hermione) must join forces with Sirius Black and Remus Lupin to not only raise Harry (and not kill each other in the process) but stop Voldemort from coming back.
It's a lot harder than it sounds, actually, especially when you add in irritating purebloods, nosey reporters and Paige's tendency to be a walking trouble magnet.
