This is definitely the better way to do it. It is a single book, divided into 2 parts.
Yes, it doesn't feel finished. Well, because that's because it isn't. But I couldn't have brought myself to not read it, as soon as I had it. I was working the nightshift and I extra went out onto the emergency stairs to get WLAN, so that the book could be delivered.
But I don't regret reading it.
I'm not sure I want to discuss it yet, so I'm not visiting the spoilers section. Maybe I'll wait until BG drops and after I've read that.
Also I managed to start another book after PT. A good one. Wouldn't be fair toward this book, if I stopped reading again, because my thoughts are with Harry. LOL
