The first book of HP, or was it sarcasm? It is the part where Christmas is coming and Harry needs to stay at school, I think. The train, btw, was from Scotland, Fort William, to Scotland, Malaig, and back. Sorry for the late reply, as I said the internet is trash here. Well, at least I have some. I travelled by boat and car to Scotland, but that was awesome too :). The nature is so wonderful here! I'm looking forward to seeing your new novel :)
PS: I kind a, almost, skipped the part after Sirius died (Book 5 of HP), I was so sad.... When I watched the movie I wasn't sad at all, but in the books.... I really cried and I couldn't really continue to read... I'm now starting to read the 6th book and hope it will take away my sad feeling...
PSS: Sorry if I mix some things up. When I want to answer things, another thing pops into my mind and I write that down and then I continue with the other part sometimes :)
