The Reading Challenge

I entered the premier's reading challenge a few days ago (once I found out about it), and when I read the reading list, I noticed that there were omnibuses, separate to the single books, meaning that you would get more than one point for reading one. I also noticed that there are parts of series, but not all of them, and a bunch of shorter books, like The Greek Who Stole Christmas, so we can read these shorter ones for extra points. I also found that alot of the books that I have read this year are not on the list.
