I just finished a second reading of the half blood prince and a 
couple of things stuck out.  1) Hagrid overheard Snape and Dumbledore 
arguing about Snape promising to do something and not wanting to but 
Dumbledore insisting he do it.  2) At the end when they're on the 
tower, Dumbledore begs Snape. He says please at least 3 times.  I 
can't believe Dumbledore is begging for his life.  I can see 
Dumbledore maybe begging Snape to reconsider going back to the dark 
side but that doesn't really ring true either.  I think he was 
begging Snape to go through with killing him.

Of course, I'm still not totally convinced Dumbledore is dead.  He 
tells Malfoy that the Order can hide him.  Malfoy replies that LV 
would kill him (Malfoy) and Dumbledore says that "you can't be killed 
if you are already dead".  He said they could hide Malfoy in ways 
(Malfoy) could not even imagine.  I didn't catch this the first time 
around because I was racing to see how it ended but everything here 
leads me to believe that we will see that Snape has been working for 
Dumbledore.

I can't believe the book has only been out since July 05.  It seems 
like it's been years.  Any idea when the next will be published?
