That's how long it took me to read the new Potter (1.53am - 4.18am).
Very, very, very good.
The death is a shock and also has the same "nah they're not really dead" feel about it as Sirius's in Order of the Phoenix.
The Half-Blood Prince is a real shock, I couldn't believe that it was that character.
Hermione and Ron row a lot, Ron gets a girlfriend (not Hermione), Harry gets a new girlfriend (also not Hermione, she does get to snog someone though), There's both a new Defence Against The Dark Arts teacher AND a new POTIONS teacher, and it's a lot more grown-up than the last one and not quite so angry.
I would write more but I'm aware that a) no one else has read it yet and I don't want to spoil it for them, and b) I have had two and a half hours sleep and need to work on waking myself up before work!
Plus, I want to finish reading my new Mike Ripley book!
