The Children Who Lived

Request by Mrs-Ginny-Evans-Granger-Potter. Heavily AU. Ginny and Hermione were orphaned and left with no family, so they were adopted by the Potters. A blood adoption that makes them family to Lily, James and Harry in every way but birth. So that night when Lily and James died, Harry wasn't alone. He and his sister all survived the killing curse and became the Children Who Lived.
