Harry Potter is the modern Star Wars for me, it's the only series that I really get hyped over. I love the books because I feel like their so skilly written and are so air-tight considering the immense plot taking place over the course of all 7 of them. These books are the reason that I got back into reading again, so I really feel like I owe a lot to J.K. Rowling for sharing her talents with the world. as far as characters go, I'd show up dressed as Kingsley Shacklebolt. he's a big dude, he's tough, and he was the first black Minister of Magic, so he's like their Barack Obama. Order of the Phoenix was also my favorite book and he's first introduced in that one, so I'd have to go with Kingsley.
