Lily Luna Potter is the daughter of Harry Potter, better known to the Wizarding World today as the Chosen One, or just as the defeater of Voldemort. It seems to be a normal fifth year at Hogwarts for Lily, but when running away from her brother she finds the Room of Requirement. Inside there is a mysterious and alluring cabinet that, when touched, sends her back in time to 1976, when her grandparents (including her namesake, Lily Evans) were in their fifth year. Will she be able to make it back to her own time? And if so, how? Follow Lily as she meets the marauders and goes on the adventure of a lifetime... back to the past. This is a Harry Potter FanFiction, which means that all the rights to characters go to JK Rowling and not to me.
