This is Ginny Weasley out of Harry Potter (Chamber of Secrets). She belongs, as we all know, to J K Rowling. As do the books and other items of worship. The small black book in her hand is Tom Riddle, eventually Lord Voldemort. Between that and the fact that it's Halloween, most fans should be able to grasp what's going on in this picture without a lengthy explanation. Which is lovely, because i don't feel like writing one.
...and by the way, if you think she's holding the quill a bit funny, she's dropping it. Dunno why though.
