Start of the fifth year.
Don't get me wrong. I know I was complaining a bit about the lack of chapters and what a hefty tome this is, but so far it is a pretty good read. It's just also a slow read between all the characters to keep track of and the weight of the prose. Or maybe it's not all that slow and it's just the length of the text that makes me feel that it is.
It's also amusing to see people vehemently arguing against what you know has already come to pass.
