I'm almost 100 pages in but seriously starting to lose focus. I had to reread the last page a couple of times for comprehension before realizing it was a lost cause.
But, this is what we have so far: A lot of action. Those of you (OK, me) expecting the usual chunk of backstory that Rowling typically starts her books with - well, not so much here. Very little, in fact. It's like she's saying, c'mon kids - we've been through this together for 10 years now, I expect you to keep up!
Also: There's already been some major death and mayhem. That's all I'm going to say on that little matter, however.
Goodnight for now.
