As I suspected, over the last three weeks I've lost my comfortable lead on the number of books read - have only managed three books during that time, what with holidays and travelling.
Still, I'm currently "on track", as Goodreads tells me, so I should still be okay.
Sub-challenges ... well, at least I've bought fewer ebooks in September, due to the aforementioned travelling! (On the other hand, I have bought more paper books, including four different editions of the book I was travelling for, i.e. going to the signings and such - but I also got my Kindle cover signed.

)
So all in all, I'm lagging a little behind compared to where I was in the same time in August, but it was a slump I expected and it doesn't particularly worry me, as long as I get back in the reading habit again soon.
