1. Tom Riddle's Diary Voldemort's soul not included. From ThinkGeek: "Are you a lonely witch with a crush on an older wizard? And on top of that, you're a ginger? From a huge family of gingers? And you're the baby and the only girl? Yeah. We get how that goes. Well, maybe not the ginger part. If you're looking for a diary you can use to talk to the Dark Lord, or perhaps one you could stab with that basilisk fang in your underwear drawer, we have the diary for you! This replica of Tom Marvolo Riddle's diary looks like the one from Harry Potter and The Chamber of Secrets. The inside is blank, so you can start your own relationship with Voldemort."
2. Gryffindor, Slytherin, Ravenclaw or Hufflepuff scarves Whatever your house, you can show your house (and school) pride with one of these scarves. Or, you could make your own.
3. Dear Mr. Potter, edited by Lily Zolan A collection of letters from fans to the boy wizard. Featured writers include Evanna Lynch, John Green, Melissa Anelli, Andrew Sims and Eric Scull.
4. Make a personalized Hogwarts acceptance letter You could simply type it in green ink and age the paper by dipping it in tea. I’ve done this for a friend and I melted red crayon for the envelope seal. I also happened to have an ‘H’ stamp.
5. Harry Potter Page to Screen: The Complete Filmmaking Journey by Bob McCabe From Goodreads: "Harry Potter: Page to Screen opens the doors to Hogwarts castle and the wizarding world of Harry Potter to reveal the complete behind-the-scenes secrets, techniques, and over-the-top artistry that brought J.K. Rowling’s acclaimed novels to cinematic life. Developed in collaboration with the creative team behind the celebrated movie series, this deluxe, 500-plus page compendium features exclusive stories from the cast and crew, hundreds of never-before-seen photographs and concept illustrations sourced from the closed film sets, and rare memorabilia. As the definitive look at the magic that made cinematic history, Page to Screen is the ultimate collectible, perfect for Muggles everywhere."
6. Harry Potter: Film Wizardry by Brian Sibley I own this and I love it! It includes letters by Emma Watson, Daniel Radcliffe, and Rupert Grint, never before seen pictures and stories, your own Maurader’s Map, Educational Decrees, an issue of the Quibbler, your own letter to Hogwarts and more. I highly recommend this book, especially if you can't afford Harry Potter Page to Screen.
