The book I am reading is Harry Potter and the Deathly Hallows. In the book Harry is still looking for the fourth Horcrux of Voldomort with Ron and Hermione. You have to read the sixth book to know what a Horcrux is. Snape is the headmaster at Hogwarts. He does get sacked though. I am almost done with this book! It is sad a member of the Order of the Phionex died. The Order of the Phionex is brought up in the fifth book.
