I should note that I deeply dislike Ginny as of book six, and I never really liked Ron. Please don't hate me. :)
My favorite book in the Harry Potter series would be Prisoner of Azkaban. I love Remus in that book. Plus Sirius was introduced, not just mentioned like in the first one, and it seemed to be a real turning point for the series.
I have an odd interest in finding number associations JKR used, whether on purpose or not. Particularly with 2, 3, 4, 6, 7, 12, and 13. I have a ton of them I can sit and name off from her books. Example. Sirius Black spent 12 years in Azkaban, and he grew up in 12 Grimmauld Place. Thinking about it, it is sort of a premenition(sp?) of sorts for Sirius later in his life.
