As I've started reading Harry Potter and the Deathly Hallows it occurred to me that I hadn't read "Half Blood Prince" in quite some time (like over a year). And having just seen "Order of the Phoenix" at the movies that story is fresh in mind. I feel like I need a little refresher course before I can go any further on Harry's adventure in year 7 before I brush up on the important events in Book 6.
What are somethings every HP fan should know before reading HP: DH? Ive already read book 6 so theres no need to be coi in letting it all hang out. No spoilers here. Dont be shy. Let me have it the way it went down. I just need a few good reminders. Can you help?
