Ginny Weasley and the Very Secret Diary

Young Miss Weasley was always on the fringe of the trio in the original series. How is her world changed when Harry Potter becomes her brother's best friend? Who does she befriend in her year? What does the Sorting Hat whisper to her? What does Riddle say that allows him to possess her? Not simple scenes from Ginny's POV, a complete story running parallel and tandem to Harry's own.
