It is amazing what one person can do to change a story. They can influence actions, plot lines, and life choices. This is the story of Maggie Johnson, Harry's cousin and adoptive sister, as she grows up with Harry, attends Hogwarts with him, and changes his life and his adventures, forever, in the way only a sister can. AU, eventual H/Hr, Neville/OC

I haven't seen her since, not really. Not enough to make me happy, not enough to satisfy the thirst within my heart. The girl who came to Hogwarts during my last year and changed everything. The girl who saved me. The girl who saved everyone.
