Diana Granger and the Warm Lizards

Although JK Rowling initially planned to give Hermione a sister, she never came to be. This is our idea of what her time at Hogwarts might have been like - with the tensions between Houses, the growing threat of Voldemort's rise, and the beginnings of a dangerous cult that endangers those both in and outside the school. Oh, and there are lots of dragons. Reviews extremely welcome!
