I. Love. This. Book!
I stayed up all night to finish it. I really like Lupin from the first mention of him on the Hogwarts Express. I love how he believed in Harry and taught him how to face the dementors. I felt so bad for poor Sirius Black too, I really wanted for him and Harry to go live together. I also honsetly hated Snape's guts in the last few chapters, serves him right to get knocked out.
