Much of the passion for the Harry Potter novels comes from the readers being able to relate to their characters and their actions, despite the fantastical context. It seems only logical, therefore, that the themes of love and justice, so pivotal to the series, should inspire readers to go that extra mile, and they have. Just as Harry and his friends seek to make their world a better place, with the Order of the Phoenix, Dumbledore’s Army, and SPEW, so too have hundreds of thousands of inspired Potterheads around the world sought to improve our Muggle world.
