Up to chapter 15...
*wibbles*
OMG, the trio fight about killed me! The frustration and cabin fever and them sniping at each other all the time and Harry doubting his abilities as a leader was already bad enough - but the Ron/Harry fight was such a blow to the gut, I felt so sorry for both of them, Ron so concerned about his family (and how could he say Harry doesn't care about Ginny or the other Weasleys - it was so clear he did, closing his eyes and willing someone to ask about what happened to Ginny), and Harry having his worst fears confirmed. And then, Hermione being forced to choose between them, being anguished at the thought of letting Ron go, but still sticking to her convictions. "Something between them was broken" - GAH!
Thank GOD I know a bit about Chapter 19, or I'd be absolutely frantic by now...
