A Day in the Life of a Spy

AU: Who is Hermione? No one knows her real name or where she came from. Her handler has always been Severus Snape, who has trained her since she was a small child to be the perfect agent to keep Harry Potter alive despite all the things and people working against him. The greatest mystery of all, however, is one even Hermione doesn't know: her own past. (No pairing yet)
